--- Comment #54 from Alexander Larsson <alexl at redhat.com> ---
You can't mount in-process without root, but if you use bubblewrap you can
shell out to things that have a different filesystem setup as a user.

For instance:

bwrap --bind / / --bind /usr/bin /tmp/bin ls -l /tmp/bin/true
-rwxr-xr-x. 1 nfsnobody nfsnobody 32424 18 aug 18.14 /tmp/bin/true
