Devuan Jessie, mount 2.26.2-6+devuan1, only says that /run is not in
/etc/fstab unless I use:
mount -t tmpfs tmpfs /run
The "filesystem mounted or mountpoint busy" stuff should be from
getting errno == EBUSY; this won't happen if you use a virtual filesystem
that supports multiple instances.
*As far as I know*, the only way mount with a single argument is
able to determine the correct filesystem or mountpoint without reading
/etc/fstab is if you add the "remount" option.
HTH,
