# $FreeBSD$
Apply a consistent style to most of the etc scripts. Particularly, use case instead of test where appropriate, since case allows case is a sh builtin and (as a side-effect) allows case-insensitivity. Changes discussed on freebsd-hackers. Submitted by: Doug Barton <Doug@gorean.org>

Revamp rc.diskless. Split into rc.diskless1 and rc.diskless2. provide more opportunities for overriding. Clean up /etc/rc ( remove conf_dir, remove startup mount special cases, remove other special cases )

Overhaul the /etc/rc.d/diskless script by splitting it out into hostname, resolve, tmp, and var scripts. The latter three are new and were repo copied. These scripts no longer depend on being booted with and NFS root instead attempt to automaticly create mfs /tmp and /var volumes if the they are not writable. This behavior can be overridden in /etc/rc.conf. Reviewed by: luigi, pjd

# PROVIDE: resolv
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.

. /etc/rc.subr
* Simplify the population of the /etc memory filesystem. To avoid the null mount, we currently create a temporary mfs on /tmp, copy /etc to /tmp, then mount /etc as mfs and copy everything back from /tmp, then delete the /tmp mfs. The patch eliminates the temporary /tmp mfs and the subsequent copying and simply populates the /etc mfs by copying from /conf/default/etc. This requires that /conf/default/etc contain a complete copy of all the /etc stuff instead of just overrides. I don't think that is too much of an extra step in setting up a diskless environment. * Provide the ability to make /tmp a memory filesystem independent of /var. This removes the requirement that /tmp be a symlink to /var/tmp and this makes the diskless code work with the default filesystem layout. If a seperate /tmp memory filesystem is created, the 'tmpsize' environment variable is used to determine its size (default to 10 Meg). * Reduce diffs between the -current and -stable versions of these files to a bare minimum. Only the definition of the shell function 'mount_md' is different. Not Objected to by: -arch@, -small@ MFC after: 2 days

load_rc_config $name
Do not unconditionally load the configuration files for the RCNG case. Instead, load them as part of the rc.d system. This allows us to prioritize the initidiskless script so it runs before the configuration files are loaded and allows us to get rid of the exit 2 hack in /etc/rc. The exit 2 never worked anyway since it did not unset the prior configuration, causing the diskless code to not operate properly. Do a major cleanup and revamping of the diskless code for RCNG. This will be backported to the non-RCNG scripts as well as -stable. With suggestions from: Mike Makonnen <mtm@identd.net> MFC after: 7 days
