Hi

bash_vi asked me to write a short resume about how to emerge programs by using the ramfs for speedup.
Here’s how to do so:

mount -t ramfs -o size=2g ramfs /var/tmp/portage/

• The “-t ramfs” is obviously self explainatory.
• The “-o size” tells the ramfs driver how much space of the RAM should be reserved for this specific mount point.
• “/var/tmp/portage/” is the place where portage usually unpacks the source boundles and begins to compile them.

You can also put it into your /etc/fstab in order to keep it for each reboot with
echo -e "ramfs\t/var/tmp/portage/\tramfs\tsize=2g\t0\t0" >> /etc/fstab

Now you can compile your stuff within RAMFS
