Yes. I still have an unused 4th primary partition on the same hard disk.
I am going to make it extended and create 3 more partitions on it:
one — for /var/tmp/notmfs, another — for /var/log and the 3rd one —
for some unpredictable purposes like installing a rescue system.
Still have not decided on their size, file system and mount options
but it would be another question in a separate thread, when I come to it.

I am currently building a new and shiny :) Gentoo system on the
1st primery partion of this disk, that actually contained old /var/tmp,
because I am a bit afraid to update my old and still working Gentoo
system on the same hard disk that I have not updated for about 9 months.

Moreover, I have changed profile from not used for a long time
one to
and already found out a lot of not wise solutions like alsa + pulseaudio
with initrc and the likes that I currently trying to avoid.

It is exactly what suggested in the "Per-package choices at compile time"
section of the "Portage TMPDIR on tmpfs” Gentoo wiki. So it should work. :)
