If the "no-owner" user has write access to the file they could
copy the file to a new file name(thus getting ownership of the
file), and overwriting the original file with the new file.
e.g.
[natea@us-cfe002:~]$ ls -l hosts
-rw-r--r-- 1 root root 50 May 12 12:17 hosts
[natea@us-cfe002:~]$ cp hosts hosts_new
[natea@us-cfe002:~]$ ls -l hosts_new
-rw-r--r-- 1 natea natea 50 May 12 12:18 hosts_new
[natea@us-cfe002:~]$ mv hosts_new hosts
mv: overwrite `hosts', overriding mode 0644? y
[natea@us-cfe002:~]$ ls -l hosts
-rw-r--r-- 1 natea natea 50 May 12 12:18 hosts
[natea@us-cfe002:~]$
nate
