I can't speak to the mirror issue, but I had difficulty trying to tweak
the defaults in the install on a 128G SSD:
When manually configuring the SSD, I tried to leave some extra space at
the end of the SSD. Not sure that is necessary or not. In any case, I
had a 128GB SSD, reported as 119GB. Auto config laid it out as
ada1 119GB
ada1p1 64KB freebsd-boot
ada1p2 115GB freebsd-ufs /
ada1p3 4GB freebsd-swap
I then deleted the last 2 and re-created as 100GB and 4GB, at which
point it showed
ada1 119GB
ada1p1 64KB freebsd-boot
ada1p2 100GB freebsd-ufs /
ada1p3 -15GB freebsd-swap
(I may have the -15 wrong; main point is it was negative)
After deleting and recreating in different order I managed to get it to
ada1 119GB
ada1p1 64KB freebsd-boot
ada1p3 4GB freebsd-swap
ada1p2 100GB freebsd-ufs /
but when I tried to commit it, I got the error:
Error mounting partition /mnt:
mount: /dev/ada1p2: Operation not permitted
The only way I could get it to actually write the distribution was to
use auto and keep what it came up with. Is this problem specific to
SSDs (seems unlikely)? Is there some magic sequence needed to tweak the
Auto result to get it to work?

Hello Everyone,
May be I should have searched more for answers, but after installing
FreeBSD 9 with gmirror, I am wondering if the experts here have some
recommendations for "best practices".
1. The Guided partitioning doesn't suggest any more to
create /var, /tmp, /usr, etc. file systems. Is it really the
recommendation to go with just / ?
This is a bad recommendation I think, but you can accept guidance and
the adjust to your needs.
2. Is there a way to use the old sysinstall to install FreeBSD 9?
Yes, harder to use, or no the new installer should have some more sane
defaults
3. It seems that setting up gmirror is more involved with GPT
(http://blather.michaelwlucas.com/archives/1071); now I have a mirror
for each of the filesystems /, /var, /tmp, etc. Is it OK to use
gmirror in this way at all?
4. Also, with GPT, one has to be in single user mode to synchronize
disks - correct?
3. Assuming one has enough RAM, is zfs mirror or raidz recommended
over gmirror?
gmirror, still I think
Prior to FreeBSD 9, I used to take the the sysinstall defaults with
some overrides as I thought appropriate and proceeded to set up
gmirror - it was simple and not a lot of work, and a good way to make
use of older systems...
I think the new installer is quite good, but needs some shaving around
the rough edges
Cheers
