No, it is incremental builds, for all port versions of FreeBSD except
CURRENT, because ABI change often, and it's safer to just rebuild
Right now, there are two boxes, one for amd64 and one for i386, and the
build order is the current quarterly branch for 9 and then 10, then head
for 10, 9, CURRENT and 8. Also, when there is a security advisory or
errata notice and the jails get updated, there is always a full rebuild.
This week, the quarterly branches took about 12 hours to build and had each
~6680 ports to build, and for head, the 10 build wanted to build 11744 (out
of 24k) took 15h28 to do so, the 9 wants to build 11747 ports, and has been
running for 4h50 as of right now.
If I look at last week, on the amd64 box, both quarterly only had ~700
ports to build and it took ~1h20, but on head, 10 had 16779 and took 18h26,
9 had 18638 and took 20h33, CURRENT had 24384 (full) and took 27h13, and 8
had 18652 in 19h17. That's about 90 hours of build, which is 3.75 days. I
can say off the top of my head that 2*3.75 > 7, so you can't do it twice a
week. Also, we *do* need some time to do maintenance, like updating the
host, and other stuff.
There was a few SA out today, so next week it'll be full build for
everybody, it *will* take about 20 hours for each architecture (except
CURRENT where it'll be 27h) that'll be a bit more than 5 days.
So, long story short, no, we cannot do twice a week *right now* we have
more hardware on the way, that will allow us to triple the build power, and
when that gets here, we will certainly do package more often, but it's in
