Bug#1052316: udev postinst uses update-rc.d -f remove which breaks /etc.init.d/udev transition and non-systemd boot

[Mark Hindley]

Package: udev
Version: 254.3-1
Severity: serious
Justification: Breaks unrelated software, causes boot failure on some systems

Dear systemd Maintainers,

As reported in the follow-up to #1052116[1], udev's postinst uses update-rc.d's
-f option which breaks the transition of /etc/init.d/udev to bin:initscripts and
causes non-systemd systems to fail to boot.

Michael, as discussed yesterday on #debian-systemd, I am very grateful for your
quick commit of a fix[2].

This bug is to prevent unintended migration of the broken udev to trixie.

With thanks and best wishes

Mark
