[gentoo-user] How to mount /tmp as tmpfs?

[gentoo-user] How to mount /tmp as tmpfs?

[Nikos Chantziaras]

It seems that mounting /tmp as a tmpfs filesystem isn't just a matter of 
adding an fstab entry.  Sometimes, on bootup, I get error messages:

   fusermount: error: /tmp/dsflkjslfjsdlsomegarbledname doesn't exist

Or something like that (it scrolls by very fast and openrc doesn't seem 
to log anything.)

Is there a safe way to mount /tmp early on?  It seems that mounting it 
through fstab is mounting it too late and files have already been 
created in it (which are then lost when mounting it.)

Why is /tmp being mounted by fusermount? Can you show us yout fstab
/tmp entry? Mine looks like:

tmpfs		/tmp		tmpfs		defaults,nosuid,size=100%	0 0

It's mounted like this:

# mount|grep /tmp
tmpfs on /tmp type tmpfs (rw,nosuid,relatime,size=6008324k)

Regards.

tmpfs                   /var/tmp/portage tmpfs          rw,size=8G      0 0
tmpfs                   /tmp            tmpfs           rw,size=1G      0 0

have that in fstab and never got errors.

Interesting question.

Have you perused these older threads, or possibly others like it? It
looks a _lot_ more involved than just an fstab entry.
