Debian/alpha is currently using a dpkg that uses lchown() with a patched libc.

I think that is very important that such code be in glibc if the 
stated goal that a libc built with 2.1 kernel headers can work with a 
2.0 kernel is to be honored.

Just a clarification, my only real work on these patches is copying 
files and editing syscalls.list. Geoff Keating wrote the original for 
powerpc.

That's my question too because the Debian/alpha people have asked for 
such a patch and are using it and seem to need it. I'm ccing this to 
debian-alpha so they are aware of this discussion.
