If you used it with ext2 partitions, I don't see why using it with
reiserfs would be a problem. It's all disk access.

Okay

Yep.

Hmmm... aren't there important things in /lib, namely libc?

I'm also not convinced that running /sbin and /bin binaries from a vfat
partition is a good idea. I would instead make a few large files on the
vfat partition, format them ext2, mount them via loopback and then copy
/sbin and /bin to them. At least then you'll have proper permissions and
symlinks etc will work.

It shouldn't be necessary to remove and recreate the partition with
fdisk (unless you're planning to resize it, I guess). Just run
mkreiserfs over it and see what happens.
