I missed the start of this thread, but... glibc already uses 4-byte UIDs.
This is a trauma my passwd gdbms and various hash functions have already gone
through, to widen the field width, even though the extra 2 bytes can't be
used yet. People who want libc5 can stick with old kernels too - glibc is
ready AFAIK for high UID support already, people have already had to modify
programs to make them work with it, so userspace shouldn't be given as a
reason to hold the kernel back. (though, if nobody == -2 with high UIDs,
that will really kill the size of quota files if they're still not allowed
