I don't think you could say it's ever been entirely *safe*; there's
always the potential that some update could do something to kill the
running session, and the more complex the definition of 'running
session', the more likely it is. Obviously a fat desktop on X is more
complex than a VT. I can only remember it happening to me once or twice,
but I'm not sure it's fair to say it's more likely now than in The
I suspect the 'real fix' for that is to run your yum updates in a screen
session. I say 'suspect' because somehow I never quite get around to
learning how to use screen...but it seems like just the ticket, as it
would prevent the desktop going down from killing the yum update.

What I'd actually recommend in that situation is doing 'rpm -e --justdb
--noscripts' on the 'old versions'; that will remove the entries from
RPM's database without possibly removing files that are actually part of
the newer one, or running scripts, which you don't want to happen.
In any case, that's not what's causing the 'protected multilib' thing
people are seeing in F16 now (or were yesterday), it's just an artefact
of yum trying to work around missing deps when you use --skip-broken.
