I would=

Check the man=

durin=
g creation. That might put the metadata at the end, rather then at
t=

Ps. I have never tried it this way=
 (full disk raid for boot device) using
linux software raid.
Ha!  Yes, this made a difference, thanks!  With metadata 0.90 =
I can see the 
same partitions I set up on /dev/md0, also on /dev/sd=
a and /dev/sdb.  The only 
problem now is that the Ubuntu server CD =
wants to format /dev/sda2 as swap and 
fails at that stage.  :-/

Not sure how to by-pass this.

I may
also try metadata=3D1.0 to see if this makes a difference, which also positions the RAID data superblock at the end of the device:

Sub-Version  Superblock Position on Device
-----------  ----------=
-------------------
0.9          At the end of the device
1.0  =
        At the end of the device
1.1          At the beginning of th=
e device
1.2          4K from the beginning of the device

To bypass the swap format you could= try either deselecting the format option (if it exists) or setting the p= artition type to something else.
The partition type can be set back to swap later from a livecd without ha= ving to reinstall.

Other option:
1 install to single disk

2 using sysresccd create a degraded raid1 using the 2nd drive

3 copy the partitions and date from drive 1 to the degraded raid device
4 add disk 1 to the raid

5 wait for the raid device is synchronized

6 change fstab and grub config to reflect the new disklayout
