proc mounted with wrong permission

[ezrizhu]

dr-xr-xr-x 235 nobody root 0 Mar 16 01:50 proc
from #138

currently, we're using mount -t proc proc /proc

Attempted solution

unshare --mount --map-root-user --pid --fork /bin/bash
mkdir proc
mount -t proc -o uid=0,gid=0 none proc

but we get
mount: a: wrong fs type, bad option, bad superblock on none, missing codepage or helper program, or other error.

attempted --mount-proc with unshare(1), also came back as owned by nobody and nogroup. unable to remount with gid,uid=0 aswell.
