= Bugs =
* '''Specific risk:''' Issues may occur during migration to <code>dracut</code> if full disk encryption is used.
** Likely issues:
*** Package <code>systemd-cryptsetup</code> is not installed.
*** <code>hostonly=yes</code> configuration option is not used.
** Workaround: If boot fails: setting the kernel parameter <code>rd.auto</code> might help. (Tested on Debian bookworm.)
* Note on bug status: Closed bugs do not necessarily mean the issue is resolved in your distribution's APT repository. Fixes may have been reverted upstream, making bug status verification difficult.
* <code>dracut</code> (abandoned)
** [https://github.com/dracutdevs/dracut/pull/2520 fix(crypt): Encrypted root FS handling with generic initrd #2520] (abandoned pull request for dracut)

* <code>dracut-ng</code> upstream bug reports and pull requests:
