Bug#445425: grub: Sort order of menu items is incorrect

[Frans Pop]

Package: grub
Version: 0.97-29
Severity: normal

I've been compiling some test kernels and with those I get the following
order:
Found kernel: /vmlinuz-2.6.23-rc8+cfs
Found kernel: /vmlinuz-2.6.23-rc9
Found kernel: /vmlinuz-2.6.23-rc9-test2
Found kernel: /vmlinuz-2.6.23-rc9-test
Found kernel: /vmlinuz-2.6.23-rc8
Found kernel: /vmlinuz-2.6.23-rc7
Found kernel: /vmlinuz-2.6.23-rc6

The major error here is that rc8+cfs is sorted before rc9 kernels, but
if I read the comments in update-grub correctly, the rc9-test* kernels
should also be sorted before rc9 itself.

It seems that the tests for kernel suffixes is the problem here. It
should test for the _first occurence_ of a suffix in a version and
not only check the end of a version string.
