how to do "repo" snapshots. I might have missed it or not have a full grasp
or understanding yet but would appreciate anyone sharing thoughts on how to
do it.
Very simply I want to be able using only cobbler to create a snapshot of a
repository and called it for example RH5.6-Feb which should contain the base
repo plus all updates that has been releases up until that point. I want to
be able to then create monthly snapshots for example and when I build a
server build it against one of these snapshots. If you can already do this
in cobbler I would appreciate some guidance or if not if anyone could share
how they achieve this with cobbler.
I think this is not implemented, you should be able to do it yourself for
repos that you host (have locally as files):
- 'cp -r /part/repo /part/reposnapshot'
- 'cobbler repo copy ...' to make the snapshot known to cobbler
You can do this in spacewalk but I am
not sure how much is spacewalk and how much is cobbler and I am keen to not
re-invent the wheel. For various reasons at the moment unfortunately I can't
use spacewalk to manage this so the solution has to be native to cobbler.
Cobbler is maintaining the repo just as a whole, spacewalk knows about the
packages inside. That way a clone of a channel in spacewalk (what you call
snapshot) happens mainly in the database, without creating copies of files.
I think you could be fine with the cobbler approach. This one needs more
diskspace, yet that could be reduced in creating hardlinks for files that
exist in multiple repos.
