Chjize

This changes a pristine Debian (or possibly Ubuntu or Cygwin (at least the chj-perllib target works)) install in ways that I like, including software installs and configuration modifications.

Currently uses cryptographic signatures without exception to ensure code integrity.

How to use

Note: you can get a script here that runs the same as the following. How it is meant to be used is, you check out chjize on your developer machine, and then when you want to install chjize on another machine you copy over the script and then run it instead of copying these instructions.

As root:

apt-get update
apt-get install -y git make gnupg
mkdir -p /opt/chj
cd /opt/chj
git clone https://github.com/pflanze/chjize.git
cd chjize/

You can verify via signed git tags that you've got the pristine source (note that most rules import the key to gpg, too, and as the key is included in the repository, this means that if you got a trusted checkout of this repository then this verification step can be skipped; it will properly check signatures of other repositories it fetches in any case):

gpg --import cj-key.asc
gpg --import cj-key-2.asc
version=r$(git tag -l | grep ^r | sed s/^r// | LANG=C sort -rn | head -1)
git checkout -b local "$version"
tmpout=$(mktemp)
tmperr=$(mktemp)
git tag -v "$version" > "$tmpout" 2> "$tmperr" || { cat "$tmpout" "$tmperr"; false; }
cat "$tmpout" "$tmperr"
# Check that the above command gives "Good signature", and (if warning) shows
#   my fingerprint 7312F47D9436FBF8C3F80CF2748247966F366AE9 if you don't have
#   a trust path to the key (which is signed by my older key A54A1D7CA1F94C866AC81A1F0FA5B21104EDB072 
#   (A54A 1D7C A1F9 4C86 6AC8.*1A1F 0FA5 B211 04ED B072), which you can google) 
if grep -q WARNING "$tmperr"; then grep "7312 F47D 9436 FBF8 C3F8  0CF2 7482 4796 6F36 6AE9" "$tmperr"; fi

# You can also do the more paranoid verification of running the
#   script lines shown in the tag (the lines starting with a `$`),
#   and verifying that you get the same output as shown:
sumsSig=$(perl -we 'local $/; $a=<STDIN>; $a=~ s{.*\n\$[^\n]*sha256sum\n}{}s; print $a' < "$tmpout")
sumsLocal=$(git ls-files -z | xargs -0 --no-run-if-empty -s 129023 -n 129023 sha256sum)
if ! diff <(echo "$sumsSig") <(echo "$sumsLocal"); then echo "check failure"; false; fi

Once you trust that the source is mine, run:

PATH=/opt/chj/chjize/bin:$PATH
chjize -h

for the list of available targets (the same as shown below). To e.g. only install my software into /opt/chj (and dependences, see targets.mk or the graph below), run:

chjize chj

Unlike Ansible, this caches which actions were already done, and is thus more efficient when asking the same target repeatedly (even across runs). If an action for some reason really should be re-run, unlink the file with the same name as the target.

The moduser target, or mod-user script, sets up bash startup files so that PATH is set so that chjize is found automatically.

Chjize may work with parallel builds (chjize -j2 and higher numbers), since we're now using wrappers around apt-get and apt (in bin/) that use waiting locks.

Client side automation

To set up servers, some more client side automation is desirable. For an example (just a recipe) see client-side-todo.

Current list of targets

(Note: these are copied from targets.mk via chjize README.md.)

release

graph-deps

Install dependencies to run the graph target.

key

Import cj-key.asc into the keyring of the current user.

debian_upgrade

Upgrade the system (via dist-upgrade), necessary on a fresh instance on typical cloud hostings like Amazon's.

fonts

Install some fonts, amongst them Inconsolata for urxvt.

urxvt

Install rxvt-unicode and trim it down for security and simplicity.

debianpackages

Install my preferred Debian packages that are command-line only.

debianpackages-x

Install my preferred Debian packages requiring X11.

chj-perl-debian

Install the Perl packages from Debian needed for chj-bin.

fperl-perl-debian

Install the Perl packages from Debian needed for fperl.

imageprocessing

Install Debian packages around image processing (like optipng, gimp, mat2)

cplusplus-compiler

Install g++.

cplusplus

Packages for development in C++.

git-sign

Check out git-sign; used by most other targets.

chj-perllib-checkout

chj-perllib

Install (via symlink) chj-perllib. These depend on fperl now, thus that is installed as well.

chj-bin-checkout

chj-bin

Install chj-bin.

debian-emacs

Install GNU Emacs via APT.

emacs

Install debian-emacs.

chj-emacs

Checkout chj-emacs. Does not run make in it.

emacs-full

Install emacs, including cloning chj-emacs in /opt/chj and running make which installs further Debian packages (including GHC, currently); you still also need to run make per user in .chj-emacs after mod-user to get the local checkouts and symlinks, though.

wget

Install wget from Debian

get_codium_deb

vscodium

Install vscode from a binary off GitHub, WARNING: just hashed once on first retrieval. HACK, unfinished: needs slim-desktop or similar to be installed or add exact dependencies to the action, or run apt-get -f install for fixing it up.

fastrandom-checkout

fastrandom

Install fastrandom.

cj-git-patchtool

Install cj-git-patchtool.

locales

Automatically configure some (English and German speaking) locales.

debconf-noninteractive

Automatically configure debconf to be in Noninteractive mode (run this to avoid other targets waiting for inputs; also, it will be the only mode that works with -j2).

chj

Check out the last tagged versions of various repositories into /opt/chj (uses signed tags via git-sign to ensure you get what I signed)

chj-x

Chj including parts requiring X11

dotconfig-xfce4-checkout

Check out Xfce4 .config files, which are used by chjize-xfce-setup.

xfce-local

Xfce4 desktop, local. Comes with /opt/chj/chjize/bin/chjize-xfce-setup to configure Xfce4 the way I like (optionally run afterwards--see message emitted by this target for some more detail). NOTE: better do not use this target directly, but rather use xfce4_load_profile or one of the ..-desktop ones.

xfce-server

Same as xfce-local, but tries to avoid installing the xserver packages.

xfce4_load_profile

load_profile

Set up Debian so that a graphical login will read the ~/.profile file (which they stopped doing at some point, dunno why); currently only implemented for Xfce.

moduser

Modify the /root, /etc/skel, and if present /home/chris directories to use a checkout of chj-home; it should safely store previous versions of your files in the Git repository that's at this place before checking out my versions, see them via gitk --all. This also sets up emacs to work nicely with Gambit, see below. Note: if there is a .git directory in those directories before, it will ask whether to continue by first moving those to /root/.trash/.

If you want to modify a particular user's home without affecting the other users, instead run /opt/chj/chjize/bin/mod-user as that user (in its home dir)

Module-Locate-checkout

Module::Locate has no signature on CPAN, thus I forked, verified and signed it myself.

Module-Locate

Test-Pod-Snippets-checkout

Test-Pod-Snippets

Test::Pod::Snippets, has a CPAN signature but for ease of checking I forked, verified and signed it myself. Depends on libpod-parser-perl from fperl-perl-debian.

fperl-test

fperl-noinstall and the necessary dependencies to run its test suite. Run the test suite.

fperl-noinstall

Install the Functional Perl library and its dependencies. Currently installs dependencies only from Debian, and Functional Perl itself via Git and checks the signature, thus is secure and won't ask questions (assuming debconf-noninteractive was run). Does not actually run make install, thus Programs using functional-perl need to use lib /opt/functional-perl/lib;! For a full installation, use the fperl target.

fperl

This is the fperl-noinstall target but also does run make install. (This still does not access CPAN, and thus is still secure.)

gambit-checkout

gambit

Install a patched version of the Gambit Scheme system.

cj-qemucontrol-checkout

cj-qemucontrol

Install cj-qemucontrol.

dnsmasq

Install dnsmasq from Debian. (Used by serve-dhcp from chj-bin.)

qemu

Install Qemu, cj-qemucontrol, dnsmasq, and run qemu-adduser to create the user specified in $QEMU_USER or the default qemu if not given, and give it the necessary permissions.

chroot-desktop

Desktop things still needed in a chroot (via chrootlogin tool from chj-bin) running inside a deskop which is installed on the host.

slim-desktop

Xfce4, desktop packages.

real-desktop

slim-desktop, but also setup for real hardware desktops/laptops (not VPSs or VMs).

perf

linux-perf and perhaps in the future other performance benchmarking tooling.

full-desktop

slim-desktop, but also removes pulseaudio and installs jack, and removes the login managers. Xfce4 has to be started via startx from the console after this! (That latter part was a hack to work around some issues in Debian stretch / get what I wanted.)

full-desktop_autoremove

The full-desktop target but also runs apt-get autoremove to free up the space taken by now unused packages.

dnsresolver

Install and configure a local dns resolver (unbound).

mercurial

Install mercurial, and hg-fast-export from either Debian or upstream source.

earlyoom

Install earlyoom (and, todo: configure it)

security

Security relevant actions, like divert cupsd so it never runs by accident.

system

Ensure basic system readyness for any system.

fail2ban

fail2ban, with some config tweaks for stricter SSH blocking

ssh-server

SSH service

slim-vncserver

Server side VNC setup, to be used via client side VNC setup. Currently assumes a single user will be used to run the VNC server as (hard codes ports).

full-vncserver

Server with VNC and Xfce4 desktop plus common chj packages. Note the message about finishing the setup.

swap

Create and activate (including adding to fstab) a swap file if none is already active. Size is automatically chosen to be the same as the RAM size or enough to give a total of RAM+swap of 3 GB.

virtualmem_3GB

Enable swap if there is less than 3 GB of RAM available. (Only provides 3 GB of virtual memory if there is at least 1 GB of RAM! But with 512 MB of RAM Gambit compilation would be swapping so much that more swap wouldn't be helpful anyway, so leave it at just what the swap target provides.)

nosudo

Remove sudo (often provided by images) since it's a security issue. Since this will lock you out from acting as root unless you have enabled corresponding access, you have to set SUDO_FORCE_REMOVE=yes before running this target or it will fail. If instead you want to keep sudo installed, set NOSUDO=no.

nosudo-auto

Runs the nosudo target except it will force removal even without SUDO_FORCE_REMOVE=yes if it can ensure that the root login can be used: either since root was not logged in via sudo, or, it is an ssh login, in which case the authorized_keys are copied to the root account--NOTE that this still will you lock out if you actually log in via password instead of a key! Still is a NOP if NOSUDO=no is set.

set-x-terminal-emulator

Set x-terminal-emulator in Debian's alternatives system to /opt/chj/bin/term, which uses urxvt.

firefox

Install Firefox from Debian.

gimp

Install Gimp from Debian.

unison

Install unison from Debian (console version).

guix

Install guix from Debian. Upgrades system to Debian Bullseye!

coworking-user

Create a new user for co-working ($COWORKING_USER, coworking by default); run .chj-home/init, giving it $CHJIZE_FULL_EMAIL as fullname/email input if present; copy ssh keys from root to it.

schemen-lili

Check out and build lili as the schemen user.

root-allow-login-from-coworking-user

Allow coworking user (again, ${COWORKING_USER-coworking}) to log into the root account via ssh root@localhost (as a sudo replacement).

coworking

Full set up of a user with Xfce desktop, various programs (like chj-bin/fperl/emacs, Firefox, Gimp, Unison), and VNC server for co-working. Requires VNC passwd file, run on your desktop: scp .vncclient-passwords/passwd root@$server:/opt/chj/chjize/tmp/. Set the CHJIZE_FULL_EMAIL env var to the email address with full name if you want the coworking user to be set up with it (default is empty strings).

schemen

Set up for Scheme mentoring: coworking target (see there for details), plus Scheme.

slim-desktop-server

slim-desktop, but then remove xorg and xserver-xorg packages. This is a horrible HACK for cases where they should never be installed in the first place but I can't figure out why they are.

rustc

Packages for compilation/installation of programs in Rust (e.g. chj-rustbin)

rust

Packages for development in Rust

dev

Packages for development (including what cj50 needs, and valgrind, but excluding documentation packages like pandoc)

dev-x

Packages for development including those requiring X11

dev-doc

Packages for "documentation development": pandoc, and debianpackages.

chj-rustbin-checkout

Check out chj-rustbin.

chj-rustbin

Install chj-rustbin.

cj-unattended-upgrades-checkout

cj-unattended-upgrades-server

Set up cj-unattended-upgrades on a server (no claws-mail installation).

cj-unattended-upgrades-desktop

Set up cj-unattended-upgrades on a desktop, which includes claws-mail.
