[opensuse-autoinstall] custom rules
Hi,
I need to match against some hostnames for selecting a profile. I have
sth. like
<rule>
<custom1>
<script>
<![CDATA[
#!/bin/sh
. /var/lib/dhcpcd/dhcpcd-eth0.info
echo -n $HOSTNAME
]]>
</script>
<match>*</match>

If it's not too hard to do it at boot time, rather then trying to script
it to know specific hostnames, and then having to update the script
anytime that list changed, you could just add some keyword on the kernel
cmdline to trigger your special thing and do that.
Could do something like..
Add to cmdline: dospecial
Do something in script like:
<rule>
<custom1>
<script>
<![CDATA[
#!/bin/sh
if [ -n "`grep dospecial /proc/cmdline`" ]
then
echo special
else
. /var/lib/dhcpcd/dhcpcd-eth0.info
echo -n $HOSTNAME
fi
]]>
</script>
<match>*</match>

That would mean different pxelinux.cfg stuff for different hosts.

Ok, that gave me the idea. Of course I can do sth. like "case $HOSTNAME in a|b|c) echo blabla" in the custom script. reaching the same effect as your script, but by listing the hostnames in the script/profile instead of a case distinction on the kernel command line (that would be much more difficult in our setup).

Which is pretty simple if you base it off the mac address or hex value of the IP. Can easily do something like 2 config files, one that is default, one that is the special case, and just use symlinks to those 2 files based on the mac or ip.

True.. it's shell so it's pretty flexible.
Thanks for the hint!
No problem. I've gotten a lot of help of the list here and love being able to give back when I can. Our installs have gotten pretty complex but really use the power of autoyast. I've setup a system where we have a script to setup the initial pxelinux.cfg/01-<mac> files to start the install (and some files in an NFS path our post scripts use for customizations). A pre-script to rewrite the autoyast profile on the fly to set the hostname, IP, initial DNS and such (which each of our office sites and customize in a config file). Chroot and post scripts to setup the base suse install to then run our company CRM system on top of that. Autoyast has a lot of flexibility in each of these stages. Next I'm going to be working on the pre-script to do a more dynamic partitioning scheme based on disk size and requested size of swap to allow people to give more/less swap. We have some huge ram hosts for big jobs and are finding a need to play with swap values more. -- Mike Marion-Unix SysAdmin/Staff IT Engineer-http://www.qualcomm.com [Bart's up in the treehouse] Marge: "What do you think he's doing up there?"
