The default alignment was changed.
Do a 'disklabel sd0', if / starts at sector 63 then it was created
before this change was made, in which case you could dump your
filesystems, reinstall, and restore them.
As well as newer hard drives (AIUI *all* new drive models since
the start of this year have larger sector sizes), CF and SSD are
likely to benefit.

Log:
Align FFS filesystem start and end sectors so the start is on a
bsize boundary and the end fills up the last bsize chunk.
Don't change the start sector if it is the first sector of the
OpenBSD portion of the disk.
Don't attempt to align on SUN_CYLCHECK architectures. They are
attempting a different alignment.
This is an attempt to ensure that FFS i/o's are aligned for optimal
performance on newer disks that lie about their sector size.
