Control: reopen -1 "Bill Brelsford <wbr...@k2di.net>" Control: reassign -1 udev 254.3-1 Control: severity -1 severe Justification: Breaks unrelated software; causes boot failure on some systems
Dear systemd maintainers, As Bill has reported here, the new udev.postinst is breaking systems not using systemd as PID 1.

Udev claims to remove the "obsolete > conffile /etc/init.d/udev", but it's still there. However, the > rc*.d symlinks are not -- "update-rc.d udev defaults" fixes it.

AFAICS 254.1-4 was never released. With best wishes, Mark [1] https://tracker.debian.org/media/packages/s/systemd/changelog-254.4-1
