r319987 (MFC'd just to make following changes apply cleanly): Replace md(4) usage in diskless(8) script rc.initdiskless with tmpfs(5). Need to multiply the size of the disk passed to mount_md by 512 as mdmfs expects number of 512-byte blocks while tmpfs size option wants number of bytes. r324107: Enhance mdmfs(8) to work with tmpfs(5). Existing scripts and associated config such as rc.initdiskless, rc.d/var, and others, use mdmfs to create memory filesystems. That program accepts a size argument which allows SI suffixes and treats an unsuffixed number as a count of 512 byte sectors. That makes it difficult to convert existing scripts to use tmpfs instead of mdmfs, because tmpfs treats unsuffixed numbers as a count of bytes. The script logic to deal with existing user config that might include suffixed and unsuffixed numbers is... unpleasant. Also, there is no g'tee that tmpfs will be available. It is sometimes configured out of small-resource embedded systems to save memory and flash storage space. These changes enhance mdmfs(8) so that it accepts two new values for the 'md-device' arg: 'tmpfs' and 'auto'. With tmpfs, the program always uses tmpfs(5) (and fails if it's not available). With 'auto' the program prefers tmpfs, but falls back to using md(4) if tmpfs isn't available. It also handles the -s argument so that the mdconfig interpetation of unsuffixed numbers applies when tmpfs is used as well, so that existing user config keeps working after a switch to tmpfs. A new rc setting, mfs_type, is added to etc/defaults/rc.conf to let users force the use of tmpfs or md; the default value is "auto". Differential Revision: https://reviews.freebsd.org/D12301 r324108: Remove spurious $flags; it's a paste-o from copying the line from rc.subr. Also, add a comment documenting the args passed to mount_md().

Make fsck_y_enable default to passing pass -R to fsck_ffs(8) in addition to -y. To me, fsck_y_enable means "try as hard as possible", and without -R, it... well, doesn't.

r316342: Consolidate random sleeps in periodic scripts Multiple periodic scripts sleep for a random amount of time in order to mitigate the thundering herd problem. This is bad, because the sum of multiple uniformly distributed random variables approaches a normal distribution, so the problem isn't mitigated as effectively as it would be with a single sleep. This change creates a single configurable anticongestion sleep. periodic will only sleep if at least one script requires it, and it will never sleep more than once per invocation. It also won't sleep if periodic was run interactively, fixing an unrelated longstanding bug.
