Currently, when postmarketOS fails to boot up, retrieving any information necessary to root cause the issue is non-trivial, requiring building a custom initramfs with debug-shell enabled and then manually copying out data. Let's improve the situation by exporting logs automatically on boot failure. This is safer than just exposing a root shell but still provides a whole lot of useful info that should make duplicating and triaging issues much easier for developers. This commit implements the functionality and includes some generally useful data. We then generate a README and expose files for each command/log as well as an archive that can be easily attached to a GitLab issue. To help with triaging, also record the version of the postmarketos-initramfs package and hash the init.sh and init_functions.sh files. For testing purposes, you can trigger the log recovery mode on-time by creating an empty file named ".pmos_export_logs" in the /boot partition. Signed-off-by: Caleb Connolly <caleb@connolly.tech>
