reassign 409240 kernel-package
thanks
Hi,
Thanks for the report. Part of the problems you encountered
are fixed in the latest kernel-package, but there is at least
one bug.

This is the bug in the postinst.

This part has been fixed by using readlink -q -m:
__> ls -als /bin/bash
672 -rwxr-xr-x 1 root root 677184 2006-12-11 15:20 /bin/bash
__> readlink -q -m /bin/bash
/bin/bash

The readlink -q -m bit is the correct one; the first
invocation only works for links; the seconf one follows every link in
the path, without requiring it to exist, or caring if it is a real
file.
