non-clone cmd line argument so the new device is created and can be used;
and re-setup operating state to reflect the newly created device

decide if we should adjust the default route and /etc/resolv.conf.
Fix the delete of the default route. The if statement was totally bogus
and the delete only worked due to a typo. [1]

lease: track the current bssid and if it changes (as reported in an
assoc/reassoc) event only then kick the state machine. This gives us
immediate response when roaming but otherwise causes us to fallback on
the normal state machine.

'get'. Since rtmsg() always gets called and returns 0 on success and -1
on failure, it's possible to exit with a suitable exit code by calling
exit(ret != 0) instead, as is done at the end of newroute().

replace this with vinum.4, but that's the kernel interface manual, which
is not appropriate in my understanding. I think that gvinum is a suitable
replacement for this.

for a configurable number of seconds, spin the disk down. Spin it back
up on the next request.
Notice that the timeout is only armed by a request, so to spin down a
disk you may have to do:
atacontrol spindown ad10 5
dd if=/dev/ad10 of=/dev/null count=1
To disable spindown, set timeout to zero:
atacontrol spindown ad10 0
In order to debug any trouble caused, this code is somewhat noisy on the
console.
Enabling spindown on a disk containing / or /var/log/messages is not
going to do anything sensible.
Spinning a disk up and down all the time will wear it out, use sensibly.

doing the MNT_RELOAD, pass in "ro" and "update"
string mount options to nmount() instead of MNT_RDONLY and MNT_UPDATE flags.
Due to the complexity of the mount parsing code especially
with respect to the root file system, passing in MNT_RDONLY and MNT_UPDATE
flags would do weird things and would cause fsck to convert the root
file system from a read-only mount to read-write.
To test:
- boot into single user mode
- show mounted file systems with: mount
- root file system should be mounted read-only
- fsck /
- show mounted file systems with: mount
- root file system should still be mounted read-only

Make both these limits a sysctl, so it is easy to change the limit.
If the userland part of ipfw finds that the sysctls don't exist,
it will just fall back to the traditional limits.
(100 packets is quite a small limit these days. If you want to test
TCP at 100Mbps, 100 packets can only accommodate a DBP of 12ms.)
Note these sysctls in the man page and warn against increasing them
without thinking first.

whether fs_bsize is larger than MINBSIZE, which is larger than the
value that is used to compared with fs_bsize, the sizeof fs, so the
check followed, will be always true.
By inspecting the code and some old commit log, I believe that the
check must be that *fs_sbsize* is larger than sizeof fs. We round
up the size to nearest dev_bsize, as the smallest accepted fs_sbsize,
personally, I think this can be even changed to equal, because this
number is mostly an invariant in file systems.
With this check, fsck_ffs(8) will be more picky and has better
chance rejecting bad first superblock rather than referring to bad
value it supplied, thus gives better chance for it to check the
filesystem carefully.

from socket buffer fill events is common, and sequence numbers wrap
quickly enough that data corruption is possible. TCP solves both of
these problems without imposing significant overhead.
