I would like to use the Posix ACL in Debian so recompiled my kernel with the option for "reiserfs posix access control lists" and download the acl package for the commands to work with it. However, although setfacl seems to work for the standard owner/group/users system when I specify a user ala:

setfacl -m user:geneanthony:rwx filename

I get an error telling me operation not supported. I don't know if there's something else I'm supposed to do to get this going. Any help?
