Hi all,

this could cause a clash if I create a netns with name ending with .mounted.

$ sudo ip/ip netns add ns1.mounted
$ sudo ip/ip netns add ns1
Cannot create namespace file "/var/run/netns/ns1.mounted": File exists
Cannot remove namespace file "/var/run/netns/ns1.mounted": Device or
resource busy

If you want to go along this road, please either:
- disallow netns creation with names ending with .mounted
- or properly document it in the manpage
