I have 8Gb RAM and this setup I had was to compile larger ebuilds like: firefox and thunderbird tmpfs /var/tmp/portage tmpfs defaults 0 0 The above in fstab creates tmpfs 3.9G 39M 3.9G 1% /var/tmp/portage When I removed my setup with /etc/portage/package.env /etc/portage/env/notmpfs.conf Firefox complains it can not compile as there is not enough disk space: * Checking for at least 4 GiB disk space at "/var/tmp/portage/www-client/firefox-38.2.0/temp" ... What is my best option? Go back to previous setup with package.env notmpfs.conf or increase tmpfs to 5Gb eg: tmpfs /var/tmp/portage tmpfs rw,size=5G 0 0 Thelma
