Re: [MLUG - DISCUSSION] Installing kernel 2.4

[Ryan Woodsmall <EMAIL:PROTECTED>]

Umm... Try /usr/src/vmlinuz* - the kernel is generally called
vmlinuz-something.  My 2.2.18 kernel with ext3 support is
vmlinuz-2.2.18ext3, for example.  Copy this file to /boot, and follow the
steps Igor outlined for making lilo see it and be able to boot it.

Have you ever compiled a kernel before?  If no, I really really REALLY
would suggest not starting with 2.4; maybe just try to recompile the
kernel that came with your distro or 2.2.18 to cut your teeth.  The 2.4
series might also need quite a few tools updated, unless you're running
Redhat or Mandrake 7.x.

Kernel installs are not something that you want to screw up, but you can
always save yourself  by keeping an old kernel around and in your
/etc/lilo.conf file.  Kernel 2.4 has some problems as well.  Read some of
the kernel dev lists for more info, but I understand that there are some
file system corruption problems in 2.4.1 (albeit not very common).  Still,
a nasty bug, that.

As a sidenote, has anyone played with ext3?  It's pretty nice and
seemingly stable, even though it's only at version 0.0.5e.  I'll be
rolling it out on 120-odd machines in the GCB labs pretty quick, because
watching a 16 GB partition fsck for 10-20 minutes is a mind-numbing
experience and a real show stopper when you have to get work done.
