>Description:
When using default partition options for entire disk offered in 'bsdinstall' the second partition is not started on a 1M offset as recommended by the FreeBSD Handbook. From the problematic default install:
# gpart show ada0
=> 34 125045357 ada0 GPT (59G)
34 128 1 freebsd-boot (64k)
162 117440384 2 freebsd-ufs (56G)
117440546 6250496 3 freebsd-swap (3G)
123691042 1354349 - free - (661M)
162 is the issue. On properly offset partitions, ada0p2 should start at offset to 2048.
>How-To-Repeat:
Install FreeBSD-9.0-BETA3 from memstick and in partitioning dialog: accept "guided" > "entire disk".
>Fix:
Change partition after freebsd-boot to a fixed offset of 2048 eg: ... -b 1M ...
