KickStart network install

Tue Nov 8 20:35:43 UTC 2005

I run kickstart via cdrom off nfs........across a network...

Yes the docs suck big time....in fact bloody useless...

My process is like this (please note these settings suit my network, IPs
etc will need altering to suit you,

Take RH cdrom1 iso that is the latest update 5 or 6 or something and
burn a cd (in fact burn all 4~5).

Copy the contents of cd1 to a folder.

Eg,

~/scsi-iso-as3-32-5-oracle

Cd ~/folder/scsi-iso-as3-32-5-oracle/isolinux/

Vi isolinux.cfg

Add these lines,

At the top,

default cdromks

add in the default,

label cdromks
  kernel vmlinuz
  append ks=cdrom:/ks.cfg initrd=initrd.img

save and exit.

Cd ../

Now create the file you just made a pointer to

Vi ks.cfg

You can now burn your own Iso.

I use this (as one line),

mkisofs -o ../cd.iso -b isolinux/isolinux.bin -c isolinux/boot.cat
-no-emul-boot -boot-load-size 4 -boot-info-table  -l -r -R -v .

>From here I samba mount my XP cd burner equipped laptop and burn the
cd.iso with roxio.

Copy the RPMS off the 4 cds, carefully keeping the sub folder layout on
your cds to what will be your exported nfs mount point.

Eg,

/home/share/redhat/rhas3-32-5

>From the "/etc/rc3.d/S99zzzcustom" file I load a script S99zzks which on
the next reboot then does my customisation like setting up sys admins
up, setting up ssh, patches the box from redhat, hardens to cis-security
standards....installs and configures applications...

Basically a bare metal restore in 45 mins....

not sure yet. first time I have messed with Kickstart. Sorry for the
lack of
info in my question. I will try it out first and ask again if I get
stuck. I
was just wondering if there were any more detailed, updated docs out
there

thanks
