You would if you tried to update the kernel (thus removing the old kernel
which is a dependency of the cman-kernel packages). However, _normally_
you DO NOT want to upgrade a kernel - you instead install a new one,
reboot into it at some time in the future - and only when everything is
verified to be working do you uninstall the old one. You often have more
than one kernel installed at once (I usually keep a UP kernel, an old
verified working SMP kernel, and the newest SMP kernel which is currently
being used). Furthermore not every module fits with every kernel so I
can't imagine how this could be fixed automatically with the above
notes... I guess having some sort of automagical build system in place
could possibly work? To be executed at kernel install... But even that
would not always be correct.
Cheers,
