1024-byte boundaries. For many years this was a reasonable
assumption. However, in recent years we have begun seeing
devices with 2048-byte sectors. These devices return errors
when dump tries to read starting in the middle of a sector
or when it tries to read only the first half of a sector.
Rather than change the native block size used by dump (and
thus create an incompatible dump format), this fix checks
for transfer requests that start and/or end on a non-sector
boundary. When such a read is detected, the new code reads
the entire sector and copies out just the part that dump

- 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.

result of an incomplete migration. An incomplete migration is
one where the MBR is not turned into a PMBR after creating the
GPT. This early in the game it's more convenient to allow the
inconsistency, because that avoids that we have to destroy the
MBR partitioning for now.
arbitrary commands when devices come and go in the device tree (which is
different than the /dev directory).
This is an initial version. Much of the planned power isn't here.
Instead of doing the full matching, we always run /etc/devd-generic.
/etc/devd.generic will go away at some point, I think.
I'm committing it in this early state so I can start getting feedback
from early adapters.

when using '-p' with reboot, and the power down action failds, reboot
the system normally. The behaviour of 'halt -p' and of shutdown(8) is
unchanged.
Approved by: roberto
'-p' is used on the reboot(8) command line.
This is intended for use when you want to attempt a power down
action, but you want the system to reboot (not halt) if the
power down action fails.
This is typically useful when the power-off action performed by
the kernel consists in signalling an uninterrupted power supply
that it should shut down its inverter if mains power has not returned.
The behaviour of shutdown(8) and init(8) is not modified;
only the behaviour of invoking 'reboot -p' manually is
modified, and then only in the case when a power-down action
fails.
