I have a partition setup script that uses $hostname if set or VolGroup00
if not. For some reason, the $getVar is not setting the default value (in
the above example TESTing) when the var is not found ($mac_address)
My script is as follows and will always fail if I do not set hostname when
setting up a system.
#set $hostname = $getVar('$hostname', None)
#if $hostname == None
#set $vgname = "VolGroup00"
#else
#set $hostpart = $hostname.split('.')[0]
#set $vgname = $hostpart
#end if
the #if check always fails causing the kickstart to fail, according to
cheetah docs this is valid:
To do a ``safe'' placeholder lookup that returns a default value if the
variable is missing:
$getVar('theVariable', None)
