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.		2007-07-29 20:27:54 +00:00
