Yes, though PRoot relies on syscall interception using ptrace(2), wh= ich
is inefficient (which may or may not be a problem, depending on the
application).

=E2=80=8BHow sh= ould I check it? Currently I believe that ubuntu 16.04 LTS (host os) suppor= ts cgroup for LXD (LXC containers).=E2=80=8B
Yes, but some distributions compile it out or turn it off by default= .
See
<http://git.savan= nah.gnu.org/cgit/guix.git/tree/guix/scripts/environment.scm#n517<= /a>>,
for a way to check whether user namespaces are enabled.

Not that I know of, but I don=E2=80=99t think it would help the non-= root use
case.
=E2=80=8BYes, I a= gree, it would make it really easy for people wanting to try guixsd and inf= act use in production inside lxc container. Also, from testing point it wil= l be really easy. beside container utility provided by guix. May be not the= highest priority for the developers right now.
