I never used tmpfs for portage TMPDIR before and now decided to give it a try.
I have 8GB of RAM and 12GB of swap on a separate partition.
Do I correctly understood https://wiki.gentoo.org/wiki/Portage_TMPDIR_on_tmpfs
that I can safely set in the fstab the size of my tmpfs to 12GB so
that the chromium
could be emerged in tmpfs (using the swap) without the need to set notmpfs.conf
for chromium and the likes.
And I am going to set the whole /var/tmp/ on tpmfs instead of just
/var/tmp/portage
Is it ok?
If you're not using ccache, then you don't need /var/tmp to be on tmpfs.
You should only put /var/tmp/portage on tmpfs.
If you do use ccache, then you need to mount both /var/tmp and
/var/tmp/portage as tmpfs. Although if you end up swapping, it's
probably going to be slower than not using tmpfs. So unless you have
something like 32GB of RAM, it might be best to use notmpfs.conf for
Chromium anyway.
(Although I didn't benchmark swap vs notmpfs.conf. Swap being slower
than notmpfs.conf is just an educated guess.)
