Jie Yu commented on MESOS-4757:
-------------------------------
OK, ic. Maybe I can just use a large enough number (e.g., 65536)? I think
getting this number for sysconf is the right way. I can easily change that.
I guess we need a boarder discussion on whether we should do something like
this or not (per your email reply and Ian's comment).
> Mesos containerizer should get uid/gids before pivot_root.

> 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.
