Subject: Boot correct kernel

Hello,

I had generic kernel 2.6.27-7 and it worked fine. Then I installed
2.6.28 that had errors during
install, but system anyway booted to 2.6.28. When I did apt-get
install of some app in this bad
2.6.28 kernel I got error messages that something is wrong. So I
entered boot menu and booted
to old 2.6.27-7 kernel and when I tried to do apt-get install of some
app, the system again looked at
2.6.28 like current kernel !!

So I looked where does files of current kernel are copied and there
are few folders (files):
/boot/vmlinuz*VERSION*
/boot/initrd*VERSION*
/boot/System-map*VERSION*
/boot/config-*VERSION*
/lib/modules
and also menu list in /boot/grub/menu.lst

So, when you have more kernels, let's say 4 working and one bad
kernel, when the system
boots selected kernel, should the system copy all files from selected
kernel to all places where
current running system kernel should be ?? That way you will always
have correct kernel running
whole system, and all installed modules for that kernel could be
loaded looking at modinfo of modules
or modules could be sorted into folders for each kernel version.

This sounds like a packaging policy bug in your distro (and I'm guessing
your distro is Ubuntu). The LKML isn't really the place for that type of
packaging/policy issue but you might have more luck asking in one of the
Ubuntu support areas (see http://www.ubuntu.com/support/communitysupport
for the options).

Good luck!
