Hi Vagrant,

cool, thanks! though… ;-)

… I've taken this and changed the timeouts for maintenance scripts so
that I could change the 1st builders timeout to 18h and the 2nd builders
to 24h timeout.

So I guess it's rather time to unblacklist some packages, definitly on
armhf but probably even on amd64/i386? Could you maybe come up with such
a list? Probably just "all which are not blacklisted on amd64"… :)

It's great to have this documented now, even if only on the list. But I
guess thats good enough for now…

seems reasonable, yes.

thanks for this suggestion, noted.

I'm not convinced the scheduled should be much more complicated than it
already is. KISS is good. (btw, I think depwaits should be scheduled
more often…)

as said, this has been implemented now. The build network can definitly
catch up easily with new uploads *and* we will get more arm hw this
year, so… :)
