Default Manual install of FreeBSD 8.0 RELEASE after gpart

Im following this guide, "FreeBSD Install Without Sysinstall"
(cant post the url - new member)

However, I have come up against a couple of problems. The reason Im not using sysinstall is becuase ive configured my paritions manually to align to boundarys that are more SSD friendly.

Create a slice apanning all the disk after the 63 sectors required by the MBR paritioning scheme:

Code:
# gpart show ad4
63 78165297 ad4 MBR (37G)
63 78165297 1 freebsd [active] (37G)
Worked out parition sizing:

Code:
	            Label   Start(ST) End(ST)   Size(ST)    (MB)
	/     Root  ___s1a  16*        1161215   1161200    566MB 
	swap  Swap  ___s1b  1161216   18966527  17805312   8694MB
	/var  Var   ___s1d  18966528  21030911   2064384   1008MB
	/tmp  Temp  ___s1e  21030912  23095295   2064384   1008MB
	/usr  User  ___s1f  23095296  54577151  31481856  15372MB
	/???                54577152  78156225  23579073  11513MB

	* +63 Sectors is reserved for MBR slice.
Create the BSD parition scheme....
Code:
# gpart create -s bsd ad4s1 
/
# gpart add -i 1 -b 16 -s 1161200 -t freebsd-ufs ad4s1
swap
# gpart add -i 2 -b 1161216 -s 17805312 -t freebsd-swap ad4s1
/var
# gpart add -i 4 -b 18966528 -s 2064384 -t freebsd-ufs ad4s1
/tmp
# gpart add -i 5 -b 21030912 -s 2064384 -t freebsd-ufs ad4s1
/usr
# gpart add -i 6 -b 23095296 -s 31481856 -t freebsd-ufs ad4s1
Create file system 4K sectors aligned (ssd friendly), 8:1 optimal ratio so block size is 32K:
Code:
# newfs -E -s 4096 -b 32768 -U -p f /dev/ad4s1a 
# newfs -E -s 4096 -b 32768 -U -p f /dev/ad4s1d 
# newfs -E -s 4096 -b 32768 -U -p f /dev/ad4s1e 
# newfs -E -s 4096 -b 32768 -U -p f /dev/ad4s1f
gpart show reveals ->
Code:
=>      0      78165297    ad4s1   BSD    (37G)
        0            16            - free - (8.0K)
       16       1161200    1       freebsd-ufs (567M)
  1161216      17805312    2       freebsd-swap (8.5GB)
 18966528       2064384    4       freebsd-ufs (1.0G)
 21030912       2064384    5       freebsd-ufs (1.0G)
 23095296      31481856    6       freebsd-ufs (15G)
 54577152      23588145            - free - (11G)
If I use 'mfsbsd' then when I try and run the install.sh, I get 'Sorry, this must be done as root' becuase the id doesnt exist.

I did try and do what the script does direct from the console but cant get the pipe to work on the keyboard (???) so cant:
Code:
# cat base.?? | tar --unlink -xpzf - -C /mnt/install
If I use the FreeBSD livecd (8.0 RELEASE) for fixit and a USB stick with the install on it. I get a little further on...

When I try and run install.sh to copy the contents across, I get seek failed.
...becuase my root fs shows Capacity @ 107% and Avail @ -120

df

/dev/ad4s1a 1756 1736 -120 107% /mnt/install
/dev/ad4s1d 1756 308 1308 19% /mnt/install/var
/dev/ad4s1e 1756 8 1308 0% /mnt/install/tmp
/dev/ad4s1f 1756 164 1452 10% /mnt/install/usr

(thanks)
