You would need to mount it twice. Then emulated programs will use
/emul/linux/procfs and non-emulated programs will use /procfs.

However, since some time the 'linux' mount option is the default,
so on newer NetBSD this isn't necessary at all.

That's /var/shm, not /var/sh. Previously NetBSD wouldn't use /var/shm
for itself, so you needed to create something for emulated programs.
But with recent NetBSD it should just work with /var/shm for emulated
programs too and you don't need the /emul/linux/var/shm mount.

In any case, it is necessary to not replace the native entries.
You may add the /emul/linux entries, but it is not necessary
nowadays.

procfs went linux-compatible with netbsd-6.
/var/shm is used since netbsd-7.
