A few people asked to see a kickstart install, so I'll post them here. I
know this is more system administration, but it is generally useful.
This is the kickstart file. You put it on your boot floppy and call it
ks.cfg. Then at the lilo prompt type linux ks=floppy. And you walk away
and have a coffee. The last server I build took 6 minutes.
You usually have to erase the *.msg files on the boot disk to make room
for the kickstart configuration file.
If you want to have the boot floppy go immediately into the install then
change the syslinux.cfg to read:
default ks
label ks
prompt 0
kernel vmlinuz
append ks initrd=initrd.img
Then you just stick in the floppy and walk away.
There is also a good KickStart-HOWTO at one of the many LDP sites. Tells
you how to make your own custom install. I just keep everything here on
our network and just FTP anything else I need from our repository machine
on the network. Whatever floats your boat!
This file works great for 5.2, but the rpm install in the %post section
of the kickstart doesn't seem to want to work in 6.0. I've asked some @
Redhat about it so we'll see. The source for the install doesn't seem to
be on any of the redhat FTP sites so I can't tell what's wrong (the source
wasn't anywhere I could find it anyway.). I'm sure it will work by the
time Redhat is selling CDs, which will be in a couple of days.
If anyone has anymore kickstart questions, feel free to drop me a line.
It's saved me billions of hours. And it's a great way to have a set of
consistent machines.
