Hi Alan,

just quick and dirty, I am too tired for formalities. :) The following 
list contains packages, that may be too big for tmpfs and are most 
probably very time consuming to compile:

     $ < /etc/portage/package.env/no_tmpfs.conf
     # custom - 20181121 - rfischer: list packages, which are too big 
for tmpfs
     #app-editors/neovim no_tmpfs.conf
