As long as you do not need to access something from dev (FreeBSD one),
this works. As soon as you need to access something from there it
depends upon the software. If the software is doing a readdir, the
user experience will be worse. And if it does not allow to enter a
Let me see if I got this: Now I have a /compat/linux/dev directory
which means that if some Linux programme wants to look into /dev it
will see just the shm entry. If there wasn't my dev directory it
would have continued to FreeBSD's /dev...
Correct.
Can you please try a solution with devfs.conf (I never tried if it
allows to link outside of dev)?
I added the following line to devfs.conf
link /tmp shm
and removed my dev stuff under /compat/linux. And it still works ;-).
That's great.
The devfs.conf thing makes it possible to simplify the (ugly)
patch a bit:

Thanks for the hint with devfs.conf, that's a lot better!
Thanks for the patch.
