- 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="Mount root filesystem read/write"`

Luke Mewburn has indicated that they (NetBSD) are not interested in keeping the scripts under rc.d in sync with us. So, remove NetBSD specific stuff (which made our scripts more complicated than necessary). The NetBSD ident string will be left intact, both for history and also incase we wish to pull in future versions. 2004-01-17 10:59:43 +00:00			`# root normally must be read/write, but if this is a BOOTP NFS`

"-o rw" is invalid and undocumented mount option that is only present for fstab(5) compatibility, and is otherwise ignored by mount(8) (not passed to mount_* programs, and not passed to nmount(2)). "-u -o rw" worked with an old mount(8) with mount_ufs.c because "-o rw" was stripped and simple "-u" caused an update of UFS from read-only to read-write, due to inability of mount(2) to track changes in options (MNT_RDONLY is either set or not). "-u" no longer causes the transition from RO to RW, now that mount(8) was converted to use nmount(2), so an explicit change to RW is required. Keep up with this change, and use "-uw" to mount root read-write. 2005-12-02 21:33:43 +00:00			`if ! mount -uw /; then`

o Implement the stop_boot subroutine [1]. This subroutine can be used by scripts in rc.d to stop rc(8) from booting into multi-user mode when a critical or severe error condition is encountered. o Modify scripts in etc/rc.d that already implemented this functionality independently. o Document it. [1] - This subroutine was implemented in FreeBSD in rc.d/fsck. I moved it to rc.subr(8). Our version differs slightly in that it takes an optional argument to stop the boot even if "autoboot" is not set.

Check if /sbin/nextboot exists before running it. PR: 93466 Submitted by: Mats Palmgren 2006-02-17 08:34:01 +00:00			`if [ -x /sbin/nextboot ]; then`
Do nextboot -D twice during boot. The first time in rc.d/root which ensures that we can remove the file as early as possible, but shut up nextboot at this moment if the operation is failed, because /boot is not necessarily a part of /; the newly added second run is placed in rc.d/mountlate after all filesystems were mounted.
