occasion 1)
===========
We need to download -only download- a list of packages and keep it for any
posterior use, for example:
- download updates every night to update our local update server
- make a dvd update for pc's with no internet acces (great!)
To do so, first, I get a list with all necessary rpm's in every box I
maintain:
rpm -qa --queryformat "%{name} \n" | grep -v gpg-pubkey | sort >
pc_01.list
with those lists, every night my server's cron downloads all updates that
afect me:
apt-get update
apt-get reinstall -dy $(cat pc_01.list pc_02.list ... pc_NN.list)
and it updates my local repo too:
rm /srv/ftp/repo/RPMS.last/*
cp /var/cache/apt/*.rpm /srv/ftp/repo/RPMS.last
genbasedir /srv/ftp/repo/
When I need, I can:
- Test new updates in a vmware machine "without wait for download" (*)
- Apply it fastly (*) to my 5 local pc's, if everthing is ok.
- I can burn a dvd to update my home's pc, where I have no internet conetion.
- Perform fastly a new updated fresh install
- Retain versions of packages to prevent broken updrades.
(*) 11Mb/s instead 106Kb/s means about 100 times faster.
Regards.
Miquel.
