I don't know about that. I know that for ia64 the RHEL2.1 dfid let to
mirror this VFAT /boot/efi, but RHEL3 didn't. I do believe that
RHEL3-level stuff lets to mirror /boot on x86-64, but RHEL4 doesn't.
The point being that this is working quite varying way even on
mode mainstream stuff.
At least i can say that this is not first priority problem at all. As
long as there isn't reasonably well installable version at all, the
secondary problems aren't on the list :)

I'd say that sparc32 would be there eventually, but not for initial

There is 64bit glibc + lot of stuff to make 64bit gcc to build (like
xorg-x11-libs etc.). So it's ready for 64bit compilation/packages.
It's not like x86-64. It's like ppc64. on sparc the userspace has been
32bit and still is. For x86-64 the userspace is 64bit with 32bit
support, so it's really other way around.
For ppc64 i've made myself 'all way 64bit version' to be able to
maintain those 64bit parts. For sparc64 is was too much of hasle now as
most of the stuff won't easily go 64bit.
I am quite conservative on what i do risk now when i do have my
buildsystems up and working (32bit and other box for 64bit parts). When
i do have working installer, i'll be more wreckless once again as it
would be much easier to get back. Now it's installing Aurora 1.0,
updateing it to 1.92 and then updating to my own tree (initially it's
kernel 2.4, so you have to go thru that 1.92/2.6 w/o udev to get

now the building the installation images (have to make box w/

it need keyboard/fb to make images :)
