IMPORTANT: due to a drive failure, as of 13-Mar-2021, the Mercurial repository had to be re-mirrored, which changed every commit SHA. The old SHAs and trees are backed up in the vault branches. Please migrate to the new branches as soon as you can.
Secondary roles are an advanced feature without any strong use cases
currently. Having multiple ways to manage roles is confusing.
Now the 'user:role' command will just show the primary role if that is all
there is, but will list secondary roles too if there are any (which in 99.9%
of cases there won't be).
