Hi everyone,

I'd like to start a discussion about dropping (at least temporarily) the
reposync command.

The reposync command is used in lago for two things:
* Downloads locally all the packages defined in the repo conf passed (yum
config file format)
* Creates an internal_repo dir in the prefix and copies over all the packages
that match the distros used in the prefix

The advantage is that once synced, this allows installing any packages on the
vms without having connection to the internet.
The downside is that right now, it downloads everything, needed or not, so it
takes a lot of space and time the first run to cache all the packages.

For that reason on the ovirt system tests we removed the epel/centos base repos
from the reposync (it was ~20G) but as that already makes the tests require an
internet connection, makes the reposync command obsolete (it is caching only
some part of the packages).

So the idea is to drop the reposync command until we have a better alternative
(maybe a small local proxy that caches everything on the first run or something
similar)

Generally, I'm in favor. I'm wondering if we can make use of the the already existing yum/dnf local cache?

Since I really don't want to download the packages EVERY time.

What about an interim solution - create an (ISO?) with some base packages - especially for the released (3.6) binaries, that will not change as often as master and can be used?

So even if some are outdated - at least it's some of them and not all of them. And we can update that ISO with newer content once ... a month or a quarter or so.
