Notable changes:
- Removed the "disktype" argument from the -B only synopsis
form. This form doesn't touch the disk label, and doesn't
use this argument.
- Fixed the first example in the EXAMPLES section. Support
for compatibility slices has been recently dropped from
the GEOM kernels, and a bit later GEOM became standard.
- Removed the buggy notion from rev. 1.37 that disklabel(8)
may be used to define mount points; it cannot. Improve
some DOS partition / FreeBSD slice wording. Among these,
``dangerously-dedicated slice'' was just a nonsense. ;-)

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".

This will *greatly* improve dump performance at the cost of possibly
missing filesystem changes that occur between passes, and does a fairly
good job making up for the loss of buffered block devices. Caching is disabled
by default to retain historical behavior.
In tests, dump performance improved by about 40% when dumping / or /usr.
Beware that dump forks and the cache may wind up being larger then you
specify, but a more complex shared memory implementation would not produce
results that are all that much better so I kept it simple for now.

default-to-deny firewall. Simply turning off IPFW via a preexisting

manner. For example, you can now do 'ipfw disable firewall' or

The algorithm used here is to measure a moving average of the times

live filesystem. To obtain a consistent dump image, dump takes
a snapshot of the filesystem and then does a dump of the snapshot.
The snapshot is removed when the dump is complete.
Also add an operator warning that the `L' option should be used
if dump is run on a live filesystem without the `L' option being
specified. The alternative would be to silently use a snapshot
any time that a live filesystem is dumped, but this change in
dump semantics seemed too drastic at this time.
