Recommend way to use Multistrap

What is the recommended way to use Multistrap?  I'm using Jessie (Debian 8).

multistrap is not in my user path, but it is in the path of root.  I
suppose I could run multistrap as root but I presume that is not how it
is intended to be run (potentially dangerous).

How should I run it as a user?

The manpage says Multistrap needs a chroot but chroot doesn't work under
fakeroot, so therefore fakeroot can't be used.

I note there is a fakechroot package.  Is it recommended to use
multistrap with fakechroot.

I also found polystrap.  That seems like it will do everything.  Is
polystrap recommended as a good way to use multistrap?  Is it
maintained?  It's not a Debian package.

Thanks,
Brendan.
