oops. word wrap. Lets try this:
%pre (and %post if needed)
ESXIP=`awk -F "ESXIP=" '{print $2}' /proc/cmdline | cut -d " " -f 1`
ESXVMOTION=`awk -F "ESXVMOTION=" '{print $2}' /proc/cmdline | cut -d " "
-f 1`

Yea, Yea, Yea, there are more elegant ways to do this, but this should
work for you

Hi
thanks everyone for your replies. The cobbler tips I'm gonna try as a
last resort. I'm now using a VMware appliance from
http://www.rtfm-ed.co.uk/?cat=11 called the UDA. Its a simple pxe / dhcp
server build on a minimal Fedora Core 5. I'm using it to roll-out VMware
ESX servers. Because the webinterface on the UDA, it will be very easy
for the admins to accept my concept and realy use it. If I had to let
them edit all scripts on the command line, they won't accept it (it is a
windows company).
Therefore, I'm first gonna try to do things using the /proc/cmdline
options. Which, as I'm lookin' at ip=`cat /proc/cmdline |perl -e 'if (<>
=~ /\sip=(.*?)\s/) {print $1}'` is gonna give me quite a headache
figuring out how this works :-)
But then again, the result will great :-)
So, if I get this right.... I can use /proc/cmdline to read the command
line that kickstart has been called from and use the output in the
kickstart file (network section)?
Without using /proc/cmdline, I got this far:
network ip=10.0.0.20 (by hand)
%post
ESXIP=10.0.0.20
ESXVMOTION=10.0.2.20
lwp-download http://webserver/centralscript.sh /tmp/centralscript.sh
chmod a+x /tmp/centralscript.sh /tmp/centralscript.sh $ESXIP $ESXVMOTION
And in centralscript.sh I can use them like $1 and $2. Which is an
improvement, but if I'm able to use /proc/cmdline I would be the hero of
my department :p
Thanks everybode for the replies !!!
Gabrie
