I am not familiar with any "userconf" program. If it is important to the issue at hand then you will need to educate me and provide more information.

But if you want to generation discussion on how things work then I suggest one of the news groups such as comp.unix.misc or possibly you should read the faqs in news.answers. Also check out the utils specific faq here: http://www.gnu.org/software/fileutils/doc/faq/ If you cannot remove the file as root or change the ownership of the file as root then something sounds corrupted within your filesystem. The chown program is small enough that I don't think there are any hidden bugs there and so I really doubt it is a program bug. But it might be something else. You would need to provide more information before we would know. For are more complete bug report please generate a small case where this behavior you are seeing is illustrated. Send to the list the details of the operating system you are using and the --version output of the programs you are using. Something like the following. id uid=0(root) gid=0(root) ls -ld ./filename -rw-rw-r-- 1 bob bob 0 Feb 26 09:15 ./filename chown root:root ./filename ls -ld ./filename -rw-rw-r-- 1 root root 0 Feb 26 09:15 ./filename chown --version chown (fileutils) 4.1 uname -a HP-UX strife B.10.20 A 9000/785 unknown And then please use a subject that somehow relates to the particular problem you are reporting. It is very hard to sort through a mailbox where every subject is 'bug' or 'help'.
