work because it referred to plexes which were almost invariably when
referred to. Instead, deprecate the "prefer" keyword for volumes
(though it's still there for the moment) and add a keyword "preferred"
to the plex definition. The relationship is like this:
Old:
vol foo ... prefer foo.p3
New:
plex foo.p3 volume foo preferred
printconfig: Print out the "preferred" keyword for plexes where
appropriate.
Still print out "prefer" for volumes. The kernel module
continues to accept this version, but it's probably not
going to live much longer.

Rewrite minor number decoding. Now we have only three types of

subdisks no longer reflects the object to which they belong. The
super devices are high-order volume numbers. This gives vastly more
potential volumes (4 million instead of 256).

Also, put a small work around into devd to prevent a hang on boot this
would cause because select used to return 2 rather than 0 for no

remove this workaround May 7th. You have until then to upgrade your
kernel if you want to run a new devd with an older kernel.
where we want to take the disklabel filesystem type of "4.2BSD" and use
fsck_4.2bsd on those filesystems.
Add a comment about why the code is there, now that we know:
* XXX This is a kludge to make automatic filesystem type guessing
* from the disklabel work for "4.2BSD" filesystems. It does a
* very limited subset of transliteration to a normalised form of
* filesystem name, and we do not seem to enforce a filesystem
* name character set.
'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
# that I just fixed to give people a chance to upgrade.

people that are playing with devd by hand to have something happen.
Otherwise, it appears that devd isn't working because /dev/devctl is
disabled and producing no events.

'a="b" c="d" at loc=1 on busN' properly set 'c' and process the rest of

o Parse nomatch and other events differently. They are more different
than the code allowed for, so we weren't properly parsing nomatch
events. It appears this fixes some of the demand loading issues that
I was having with devd.

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.
