- Add vnode-backed swap space specification support. This is enabled when device names "md" or "md[0-9]*" and a "file" option are specified in /etc/fstab like this: md none swap sw,file=/swap.bin 0 0 - Add GBDE/GELI encrypted swap space specification support, which rc.d/encswap supported. The /etc/fstab lines are like the following: /dev/ada1p1.bde none swap sw 0 0 /dev/ada1p2.eli none swap sw 0 0 .eli devices accepts aalgo, ealgo, keylen, and sectorsize as options. swapctl(8) can understand an encrypted device in the command line like this: # swapctl -a /dev/ada2p1.bde - "-L" flag is added to support "late" option to defer swapon until rc.d/mountlate runs. - rc.d script change: rc.d/encswap -> removed rc.d/addswap -> just display a warning message if $swapfile is defined rc.d/swap1 -> renamed to rc.d/swap rc.d/swaplate -> newly added to support "late" option These changes alleviate a race condition between device creation/removal and swapon/swapoff.

- Add descriptions to most of the rc scripts. Those are mostly taken from their daemon's manpage and probably improved. - Consistently use "filesystem" not "file system". Approved by: bapt, brueffer Differential Revision: D452 2016-04-23 16:10:54 +00:00			`desc="Setup late swap space"`
