Gilbert Song commented on MESOS-4757:
-------------------------------------
[~idownes], Kevin proposed a solution for host user -> container user around
two months ago via mailing list. Could you take a look at it to see whether it
may break your cases? Thanks! :)

> Currently, we call os::su(user) after pivot_root. This is problematic because
> /etc/passwd and /etc/group might be missing in container's root filesystem.
> We should instead, get the uid/gids before pivot_root, and call
> setuid/setgroups after pivot_root.
