Title:
Unable to configure raw.id_map with multiple entries
Status in lxc package in Ubuntu:
Fix Committed
Status in lxd package in Ubuntu:

Bug description:
I am trying to map two users (999, 1001) to one of my containers. I
added both IDs to /etc/subgid and /etc/subuid. I followed by setting
raw.id_map property value (as instructed here
https://lists.linuxcontainers.org/pipermail/lxc-
users/2017-March/013034.html):
"echo -e "both 999 999\nboth 1001 1001" | lxc config set mycontainer
raw.idmap -"
However upon starting the container, I get errors (log excerpt below).
If, on the other hand, I set idmap to either "both 999 999" or "both
1001 1001" only - i.e. if I map only one user at the time, the
container starts just fine and the user is mapped as expected.
My subgid and subuid look as follows:
lxd:100000:65536
root:100000:65536
root:1001:1
root:999:1
