Kris Kennaway 687f043633 Support builds using zfs and tmpfs backing store
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.
