Subject: unshare -m for non-root user
Date: Fri, 30 Oct 2015 03:09:15 +0100 [thread overview]
Message-ID: <n0ujgc$tll$1@ger.gmane.org> (raw)
Hi,
I wonder why "unshare -m" doesn't work for an unpriviledged user:
$ unshare -m /bin/bash
unshare: unshare failed: Operation not permitted
$ echo $?
1
$ ls -l `which unshare`
-rwxr-xr-x 1 root root 14640 Mar 30 2015 /usr/bin/unshare
Funny thing: when making the binary setuid then it works.
But I would prefer a working original version in the OS repository.
OS: Debian 8
# dpkg -l | grep -i util-linux
ii util-linux 2.25.2-6
amd64 Miscellaneous system utilities
Is this a bug, or is it not supposed to work for non-root users?

Thx
