The current code relies on the tmpfs mount defaulting to 1777
permissions. If it doesn't, things break badly.
This can come up when tmpfs is disabled in the kernel and ramfs
is being used instead (the kernel will alias tmpfs to ramfs).
The default permissions for ramfs is 0755.
All Linux systems need /dev to be set up,so add code to devfs to do
this. The process devfs follows is below.
1. If static_dev is yes, nothing is done.
2. if /dev is an entry in fstab it is mounted or remounted based on that
entry.
3. If /dev is not in fstab, it attempts to mount /dev as a devtmpfs or
tmpfs depending on which is defined in the kernel; devtmpfs is
preferred.
4. If neither devtmpfs nor tmpfs is defined, it assumes the user wants
static /dev and prints a warning.

This was requested by Debian, because the minicom software, which is
available on Debian and other distros, has a binary named runscript. We
are keeping a backward compatibility symlink for now, but this allows
Debian or any other distro to safely remove the symlink.

SBINDIR and BINDIR can be set independently of PREFIX. This fixes
broken shebangs in service files when SBINDIR is set to something other
than PREFIX/sbin

There were references in the devfs script to mdev, udev and
udev-mount. These all provide the virtuals dev and dev-mount; that is
how we should refer to them.
I believe in the discussion I had with Tony and Robin about this, we
were going to change the "use" line to "need". However, after thinking
that over, I'm not comfortable doing so because someone could be running
a static /dev with no device manager.

Using the new dev-mount virtual, with udev-mount included until new udev
version is rolled out, we run devfs earlier now, before udev/mdev.
It only needs (u)dev-mount before it, so that /dev is mounted.
This opens the way for tmpfiles.d, which needs to be sandwiched in the
middle.

mounting various bits in /dev and /sys.
init.sh JUST mounts /lib/rc/init.d (and /proc for Linux systems)
To make development of this easier we now return an empty RC_STRINGLIST
instead of a NULL for empty things.
If you don't have a udev init script installed, don't reboot your box OR
roll back to an older OpenRC version.
