This commit introduces the _kiosk.service_ unit, which launches `sway`
to start a Wayland session, which in turn launches Firefox. The
`policies.json` file configures Firefox in a sort of kiosk mode,
disabling most features and blocking all but the desginated sites.
Unfortunately, running `firefox --kiosk` doesn't actually work: Firefox
apparently runs, but doesn't draw anything on the screen.
Note that we have to launch Firefox by its "real" path, since
`/usr/bin/firefox` is a Bash script, and Bash is not installed.
Fortunately, the wrapper script doesn't do anything we really care
about, so bypassing it is fine.
Unfortunately, even building Firefox with GCC fails:
> 3:30.02 [gecko-profiler 0.1.0] /../lib/gcc/aarch64-unknown-linux-gnu/14/include/g++-v14/cstdlib:79:15: fatal error: 'stdlib.h' file not found
> 3:30.02 [gecko-profiler 0.1.0] thread 'main' panicked at tools/profiler/rust-api/build.rs:104:10:
> 3:30.02 [gecko-profiler 0.1.0] Unable to generate bindings: ClangDiagnostic("/../lib/gcc/aarch64-unknown-linux-gnu/14/include/g++-v14/cstdlib:79:15: fatal error: 'stdlib.h' file not found\n")
Clearly, something is misconfigured, because `stdlib.h` does indeed
exist. I am not sure what, though, and I am getting tired of messing
with this.
Fortunately, the official Gentoo binary package project has a build of
_www-client/firefox_ for ARM64. It has a rather different USE flag
configuration than what we did, though, so we have to pull in quite a
few more dependencies.
We can't just add _www-client/firefox_ to `install.packages` because
Aimee OS runs `emerge` with `--getbinpkgonly`, which implies
`--binpkg-changed-deps=y`. This since we want to build everything
_except_ Firefox locally, the dependency graph is quite a bit different,
so Portage ignores the binary package and will try to build
_www-client/firefox_ from source.
To work around this limitation, we need to install Firefox manually in
the `customize.sh` script in two phases. First, we install all of its
dependencies in the build root (`/usr/aarch64-…`), but not Firefox
itself, to get binpkgs for them. Then, we install _www-client/firefox_
in the target root (`/mnt/gentoo`) with the `--getbinpkg` and
`--usepkgonly` flags.
Hopefully, one day I can figure out how to cross-compile Firefox (and it
doesn't take days to build once I do), and we can remove this hackery.
Deleting the initial password for `root` so we can log in to the serial
console for debugging.
