Bug#586002: initramfs-tools: should work around 'find -printf %Y' bug

[Colin Watson <cjwatson@ubuntu.com>]

Package: initramfs-tools
Version: 0.96.1
Severity: normal
Tags: patch
User: ubuntu-devel@lists.ubuntu.com
Usertags: origin-ubuntu ubuntu-patch maverick

The change to filter out looping or broken symlinks from the initramfs,
written by me for Ubuntu and applied to Debian for #575157, tickles a
bug in find (which I think also had an associated Debian bug, but I've
been unable to find it):

This was fixed in 4.5.8, which is currently only in experimental.  In
any case findutils is very deep in the dependency chain for upgrades and
I believe it would be a good idea to avoid requiring a new version of it
(I've had problems quite recently with strict dependencies on findutils
causing unresolvable dependency loops).  The following patch works
around this bug in a reasonably straightforward way.
