Chown (from coreutils-6.1) --no-dereference does not change the owner of a link, but the target of the link, also chown -R does dnot change the owner of a link. Chown of coreutils-5.97 works as expected.
works for me: # rm -f a b # touch a # ln -s a b # ls -l a b -rw-r--r-- 1 root root 0 2006-09-16 01:36 a lrwxrwxrwx 1 root root 1 2006-09-16 01:36 b -> a # chown -h vapier:users b # ls -l a b -rw-r--r-- 1 root root 0 2006-09-16 01:36 a lrwxrwxrwx 1 vapier users 1 2006-09-16 01:36 b -> a # chown --version chown (GNU coreutils) 6.1

works on my 32bit machines run `strace -f -o out chown -h rose:users b` on a machine that fails and post the 'out' file as an attachment
Created attachment 97210 [details] result of 'strace -f -o chown.out chown -h rose:users b' I did 'strace -f -o chown.out chown -h rose:users b', chown.out is in the attachment.

this is your problem: 25752 chown32("b", 1203, 100) = 0 that should be an lstat() followed by an lchown()
And what should I do? Emerge once more glibc? Juergen
looks like a bug in glibc ... i'm looking into it as i found an x86 that i can reproduce this problem on
I updated through coreutils-6.2 to coreutils-6.3 and glibc to glibc-2.4-r4. But I still have the error with "chown -h rose:users some_symbolic_link", the owner of the target and not the owner of the link is changed.

on the system where i had this problem, i upgraded to glibc-2.5 and now it's working ... can one of you guys confirm this ?
