[lxc-users] Proper Syntax for Setting raw.idmap for a container

[Gaétan QUENTIN]

in a LXD container, the syntax is:

lxc config set mycontainer   raw.idmap 'both 1003 1003'

as idmap  is a blob, i you want assign multiple values, you have to send
multilines:

echo -e "both 1003 1003\nboth 1004 1004" | lxc config set mycontainer
raw.idmap -
