Kickstart - Partitioning....possible to use whole disk for LVM without creating a LVM partition

[Andrew Simpson]

I use kernel options that are set in the grub (i.e. isolinux/syslinux cfg
files )  I pass in @vm on the append line, then in the kickstart, I parse
/proc/cmdline for all the options.

Following that, I check if [[ $"opt_vm" == "1" ]]; then.....

i then have each partition size set as a variable ( SIZE_ROOT = 20000,
SIZE_VAR = 1024, etc...).

otherwise, I have another set of partition sizes.

But basically, yes you can setup different partitioning schemes based off
of variables in your kickstart.  I do this by dumping the partitioning
information into a file (pre.ks), which is included via %include /ks/pre.ks
at the beginning of the kickstart.  Makes it fairly dynamic.
