Bug#534170: initramfs-tools: do not install persistent files in initrd on request / if necessary

[Michael Prokop <mika@debian.org>]

Package: initramfs-tools
Version: 0.93.3
Severity: wishlist


When using MODULES=netboot there are udev rules included in the
initrd like /etc/udev/rules.d/70-persistent-net.rules and
/etc/udev/rules.d/70-persistent-cd.rules - which usually doesn't
make any sense.

I'm aware that this is deriving from udev's extra/initramfs.hook
though I'd like to discuss what's the best way to get rid of
persistent files in the initrd.

Something like a "delete persistent infos" feature for initrd
generation would be nice. Building generic initrds works if the
currently running system doesn't have udev running but on a live
system building a generic initrd isn't 100% reliable.

What about providing a file /etc/initramfs-tools/conf.d/blacklist
which provides a list of files that should not be included in the
initrd (not enabled by default but just when using BLACKLIST=y in
/etc/initramfs-tools/initramfs.conf)?
