zfs:
* Enabled by use_zfs=1 in portbuild.conf
* Populate build chroots by cloning a zfs snapshot instead of maintaining
many duplicate copies. In principle this is very efficient since
everything is copy-on-write and zfs snapshot creation is almost
instantaneous. There might be additional overheads from building on zfs
though. Currently the snapshot base is hard-wired to y/${branch}@base
but should be parametrized. This also must be populated beforehand, e.g.
during machine startup
* Clean build chroots by just destroying the snapshot.
tmpfs:
* Enabled by use_tmpfs=1 and tmpfs_size in portbuild.conf
* The previous md strategy of mounting in used/, populating and then
remounting (to avoid possible races from multiple builds claiming the
same chroot) doesn't work here because tmpfs instances are destroyed at
umount. I am not entirely sure the simpler approach is free from races.
order to run certain host binaries that were kernel-dependent. We
now seem to be able to rely on the /rescue versions (and killall(1)
seems to be unused).
* Allow for ccache directories to be shared over NFS via the ccache_dir_nfs
portbuild.conf boolean
* Populate BSD.local.dist from ${PORTSDIR}/Templates and remove population
of BSD.x11-4.dist and support for XFree86 3.x
machine with the lowest number of running jobs. This worked when the
clients were all roughly equivalent, but schedules poorly when there
are some that are much more powerful (e.g. 8-core machines vs UP machines)
* We now compute the ratio of running jobs to maximum jobs and schedule on
the machine with lowest occupation fraction. This populates the machines
to equal fractions of their capacity.
* Only hardlink the old log files instead of anything else that might be
in the directories
* Add comment that old logfiles should be removed as well as packages, to
avoid duplicate versions of the same port log
do it in portbuild from outside the jail thesedays
* Ignore /var/db/fontconfig which does not get restored to pristine state
* Save copies of master.passwd and groups and check them after the build
for changes, to look for user/group additions that may not be correctly
registered in UIDs/GIDs. Future work will hopefully automatically
check against those files and make unregistered IDs a fatal condition
* Correct logic mistake that was keeping distfiles for collection when
the checksum mismatched
with very long arguments (>400000 characters).
The problem reveals for example if
/usr/ports/Tools/scripts/rmport -d print/ghostscript-gnu
is executed - it does
printf "%s\n" "... 451109 chars ..."

packages due to packages being trimmed by RESTRICTED.
While here, note that the 'missing' column will be off by the number of
duplicates in the other columns. This happens when partial builds are
restarted.
on a machine that has use_md_swap=1, allow for the possibility of reusing
a md between builds if md_persistent=1. This requires a patch from pjd
to support BIO_DELETE in md devices, but it is a big optimization when
it can be used.
There is no change in any of the individual terms; this is merely a
rearrangement.
This change undoes what I was trying to do back in 2004 of breaking up
each individual test into a grep, for readability. The performance of
the script has continued to suffer as new greps were added over time,
to the point where this is now a bad tradeoff.

No code changes (yet) except for the deletion of one duplicate
