In the days before r208307 addswap was running early in the second stage of rcorder. Somehow in the intervening period addswap got moved to the very end, which is almost certainly not what we want. This change moves it to right after kld so that for users who need it, they'll get it ASAP. 2012-02-11 06:21:16 +00:00			`# REQUIRE: FILESYSTEMS kld`
Simply things so that "#REQUIRE: FILESYSTEMS" means the file systems are fully "ready to go". 'FILESYSTEMS' states: "This is a dummy dependency, for services which require file systems to be mounted before starting." However, we have 'var' which is was run after 'FILESYSTEMS' and can mount /var if it already isn't mounted. Furthermore, several scripts cannot use /var until 'cleanvar' has done its thing. Thus "FILESYSTEMS" hasn't really meant all critical file systems are fully usable. 2012-09-11 05:04:59 +00:00			`# BEFORE: netif`

- 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.
