I don't understand your reply. Exactly *how* do we "wait until every
mirror is synchonized, become notified, then try".

Freshclam is run periodically, automatically (via cron, in our case).
Shouldn't it be freshclam's job to do things at the right time. And how
would *it* know when all mirrors are synced? Is it Talos that populates
the mirrors? Then Talos shouldn't update the DNS TXT records until *all*
mirrors are ready.

P.S. The client's mirrors.dat file is updated in 18 different places in
manager.c, which is in the freshclam subsystem.
