New:

appropriate.
Still print out "prefer" for volumes. The kernel module

Also, put a small work around into devd to prevent a hang on boot this

Add a comment about why the code is there, now that we know:

'd': now means don't do daemon().
'D': Debug
'n': Don't wait to process all pending events before calling daemon.
In the past, devd would call daemon immediately. However, this causes
a race. If anything in the boot process depends on configuring the
devices configured by devd, maybe they would be configured in time,
maybe not. Now we don't call daemon until all pending events are
processed, unless -n is specified.
# -n is actually the default for a while due to the select(2) bug in devctl

Otherwise, it appears that devd isn't working because /dev/devctl is

o Parse nomatch and other events differently. They are more different

FreeBSD 5.1-RELEASE and later:
- newfs(8) will now create UFS2 file systems unless UFS1 is specifically
requested (-O1). To do this, I just twiddled the Oflag default.
- sysinstall(8) will now select UFS2 as the default layout for new
file systems unless specifically requested (use '1' and '2' to change
the file system layout in the disk labeler). To do this, I inverted
the ufs2 flag into a ufs1 flag, since ufs2 is now the default and
ufs1 is the edge case. There's a slight semantic change in the
key behavior: '2' no longer toggles, it changes the selection to UFS2.
This is very similar to a patch David O'Brien sent me at one point, and
that I couldn't find.

upper-case alphabetical characters to lower-case ones, and spaces to dashes.
The person who added this when bringing the code from NetBSD has no idea why
he added it, and nobody on freebsd-fs came up with any cases where the icky
part (the conversion of spaces to underscores) was needed. The removal of
the upper-case conversion follows an even more obvious logic: it avoids any
sort of namespace issues. People using StUdLy caps for filesystem names
deserve everything they get. Otherwise, Efs and efs might be totally different
things, but would use the same fsck. And we don't want that, right? That
just provokes the sort of foot-shooting this would prevent.
If you have problems with this, I'll walk you through using sed on your fstab,
cause the only way you could have problems is if you spelled ufs as "UFS".
