Hey people,
I am trying to use the ksmeta="" construct to pass a list of
dictionaries through to the kickstart file where I am using a cheetah
"#for $var in $vars" loop to unravel them.
Is this possible?
Achieving that result is possible, though as you've entered it, the
variable will just be a string, not a data structure. --ksmeta in the
command line allows for "key=value key=value" ... key/value pairs
seperated by spaces. Those values aren't evaluated to be Python data
structures.
I have not really used Cheetah for ultra-advanced templating usage,
though it does allow executing arbitrary python code, so in theory,
you could pass in arbitrary strings and work on them in Python,
including evaling them to create real data structures. Whether this works
as advertised I don't know... though I could definitely use some more
advanced templating examples for the Wiki.
I'd be inclined to take a simpler approach though, and pass in simple
variables like --ksmeta="eth0=dhcp eth1=dhcp", and then check
for the values of those expressions, possibly in conjunction with "#if"
templating
#if defined $eth0 # syntax for this is probably wrong :)
some line containing value for $eth0
#end
etc
TIA
Dan
PS this is what I am trying to do;
cobbler profile edit --name=RHEL44-ORACLE10G-i386 --ksmeta="nics=[{
'dev': 'eth0', 'bootproto': 'dhcp'},{ 'dev': 'eth1', 'bootproto':
'dhcp'}]"
and the kickstart file has the following snippet in it;
#for $nic in $nics
$nic_string = "network"
#for $key, $value in $nic.items()
$nic_string = $nic_string + " --%s %s" % ( $key, $value )
#end for
#end for
