Comment 2 for bug 1699919

The thing is - it didn't get remapped. Now I have two containers mapping to the same range, both live:

pshemk@ii:~$ lxc list
+---------+---------+---------------------+------+------------+-----------+
| NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS |

| putils | RUNNING | 10.221.22.91 (eth0) | | PERSISTENT | 1 |

pshemk@ii:~$ lxc config show putils

pshemk@ii:~$ lxc config show backend

both have the same hostid, and get mapped to the same range.

Should the files on the file system belong to the same uid:gid for 2 different containers?
