Set up a local rsync mirror from any of the locally fast upstream

DVD, to point to the local mirror. Ideally, set up a kickstart file
too on the local mirror, ideally tied to a the PXE setup.
Then just use the PXE or netinstall ISO to do a kickstarted, network
based re-install. That way, you don't even have to download the DVD
images, which are quite builky. If you like, I'll post my download
scripts....
Thanks Nico,
I would like to see your scripts.
Let me put them up at github.com, and give me a day.
What I will be testing is what changes are needed to our packaged and
unpackaged applications.
Excuse the basic questions but I'm more of a developer than a sysadmin. If
I understand your recommendations the system including user accounts will be
rebuilt on each boot. So if I want to work through multiple reboots I could
put my home directory on an NFS mount and end up with fresh software but the
same environment. Correct?
That's one workable way, yes. If PXE and kickstart can be set up
correctly, the "kickstart" can even set up your NFS mounted home
directory and local authentication and sudo privileges, and the PXE
can allow a "rebuild me from scratch" option at boot time. that will
select and automatically use the relevant kickstart file. It can even
be set to auto-rebuild every time, if you want.
I've done this a lot for hardware testing, and for building clusters.
One of the limitations is local bandwidth: if you're rebuilding a
bunch of times from the upstream SL 7 Alpha website, well, that's
rude. It's hundereds of megs, possibly even Gigs, of bandwidth. Set
up a local mirror to pull from instead, and keep *that* updated.
Thanks. I'm sure others in our collaboration will be doing more extensive
tests.
Best,
Joe
Thanks again, I appreciate the help.
I've set up kickstart once, successfully and I'm ready to do battle with
PXE. Just one of quick question for now, I'm sure more will follow later:
The mirror I've started is
rsync://mirror.mcs.anl.gov/scientific-linux/7rolling/x86_64/os I think
that's all I need to maintain, correct? I'm in Los Angeles.
Best,
Joe
