Many ways to skin that cat (all equally odious to the cat). Here's an
approach..
Assumptions:
1. All machines are networked i386 arch machines (client1 .. client N).
2. One is set up as an NFS server (lets call it server1), has exported
a filesystem (e.g /share) with room for all the updates, and you have
mounted it on all the clients as /share.
On all machines, create a file in /etc/yum.repos.d called local.repo
containing:
[local]
name=Fedora Local $releasever - $basearch
baseurl=file:/share/yum/fedora/$releasever/updates/$basearch/
enabled=1
On server1:
# mkdir -p /share/yum/fedora/3/updates/i386
# yum install createrepo
(if not already there)
Start:
For X = 1 to N {
Log on to clientX. Following is one logical line...
# rsync --archive --verbose /var/cache/yum/updates-released/packages/\
/share/yum/fedora/3/updates/i386
}
On server1:
# rsync --archive --verbose /var/cache/yum/updates-released/packages/\
/share/yum/fedora/3/updates/i386
# createrepo /share/yum/fedora/3/updates/i386
Run "yum update" on all machines.
GoTo Start
Will end up with obsolete files in the updates directory as time goes
on, but yum handles that OK. Can do manual cleanup if space is tight.
Extensible to x86_64, ppc, etc.
Could also write files to removable media, consolidate on a CD, and
mount on each machine - just adjust the path in the [local] repo entry.
Can sync updates directory with a mirror server, rather than from each
machine, but you will likely be downloading things you won't need.
