- This is political nonsense.
-
- Yes, NFS is not EFS, and the differences between NFS symantics and
- common UNIX file system symantics can be, to understate the case,
- inconvenient.
-
- No, that is not what is happening here. A network file system for
- anything but a trivial network must worry more about security than the
- local disk file system. Generally, a machine can trust itself to have
- authenticated "root", but generally a machine should not trust other
- machines to have authenticated "root."
-
- If you want root on the server to be the same as root on one or more
- clients, so that chown as root would work, then you can set
- /etc/exports so that is what happens.
- Read `man exporfs` and `man exports`.

-
- That is often the best (i.e. safest and easiest) way to be root on the
- server.
