I seem to remember some talk about being able to boot a rescue image with cobbler to perform maintainence - Is this something thats possible at the moment or going to be made available?
thanks

If you already have a distro set up, it should be easy enough to create a profile that will boot in rescue mode. With RHEL, it is simply a matter of using the usual kickstart setup and defining the "rescue" kernel parameter, though you probably want to pass along enough information to boot into rescue mode without having to answer twenty questions.

Here is a simple rescue boot kickstart template that I use:
# Rescue Boot Template
# SYSTEM LANGUAGE lang en_US
# LANGUAGE MODULES TO INSTALL langsupport en_US
# SYSTEM KEYBOARD keyboard "us"
# NETWORK INFORMATION network --bootproto dhcp
# INSTALLATION TYPE nfs --server $nfs_server --dir $nfs_distro_root/$distro --opts=tcp
Where: 1. nfs server is my server 2. nfs_distro_root is the full path to my distro 3. distro is my cobbler distro
Hope this helps
Cheers, joe

Would it be interesting to have cobbler import auto-create "rescue" profiles automatically?
This seems pretty easy to do and we could ship a similar template in /etc/cobbler.
Import is already mirroring trees over http.

I think that would be an excellent idea.
I had a look at this recently, and got sidetracked.but I had a working buildiso image with rescue.
Looking back at my testing notes, I see I decided to leave the language / keyboard settings out so that rescue asks what you have?
I think I still have the patches around to add a rescue image to buildiso.

Yeah, I'm not sure why that wasn't applied, possibly because the kickstart file wasn't supplied? Either way this would be useful.
The idea about the previous email was about auto-creating distro/profile objects for the rescue item, and if we do that they will show up on the disc automatically.
In which case, it doesn't have to be buildiso specific and will also show up in PXE menus and can be sent to specific systems, etc.
