Speaking of Aurora, last time I was playing with it, RAID on boot was not
supported.  So you couldn't have /boot on RAID1, and also attempting to do so
would trash either partition table or file system superblock (!?), depending
which order you attempt to do things.  I don't know if it was problem with
Aurora or with kernel.  Have you attempted doing anything like that in your

Definitely.  If it takes more than 5 minuts of work to get sparc32 kernel
working, it is not worth it.  And even than it would be waste of disc space on
mirrors to store sparc32 distribution.  Its like having i386 (as in 
boots on an
Intel 80386 or 80386SX processor) distribution.  Simply way too slow.

Is entire userland going to be 32-bit only, or there will be option to install
32bit or 64bit version of particular package (like on x86_64)?
