While I agree with you in need of aligning [first] partition, I'd like
to behold, that gpart show size in blocks, not in megabytes, so to align
partition to 1 mbyte on 4K-align HDDs you might execute "gpart add -b
2048 -s 64K -t freebsd-boot ada0" ( 2048 blocks * 4096 kbytes =3D 8 Mbyte=
,
in case of "plain" HDD 2048 blocks * 512 bytes =3D 1 Mbyte, which, I
think, is a pretty good).
Moreover, I don't see why freebsd-boot partition should be more than
512K, if even 64K are currently just enough for FreeBSD. Looks like old
and famous Bill Gates's sentence, I know, but however :)
