    thats weird, i've never had that issue. however, if there was ever the occasion where something from yaourt failed, i never assumed it was because of the tmpfs.

    what i don't get is why don't distros use ramfs? that dynamically expands, so you pretty much only use up what you need.
    Try building kernels with packer. tmpfs will run out of space.

      If you read the article, the answer is in it. https://fedoraproject.org/wiki/Features/tmp-on-tmpfs is the specification and such programs should be fixed to use /var/tmp instead of /tmp. A direct quote

      "My CD burning application writes huge .iso files to /tmp, and this breaks on tmpfs!

      The application should be fixed to use /var/tmp. "

        Have the Nvidia binary drivers been fixed? They used to break when /tmp was tmpfs.

          Mine are also tmpfs and I also picked up the habit when a Gentoo user (long since switched to Ubuntu). I have 24 GB for each so I don't have issues with ISOs being created there. On server systems I have 64GB allocated.

          I've yet to see a file in /var/tmp - does any software actually use it?

            Binary blob has had no problems with this for a while now. I ran my ThinkPad T410 containing an nVidia 3100M in such a configuration ever since I got it back in January 2011. (Don't have that laptop anymore now, though.)

              It doesn't swap, and an ordinary user can fill the ram with ramfs (=local DOS).

                Already

                I already use tmpfs for /tmp today, and have been doing so for a while to save disk writes on my solid-state disk (SSD).

                  I have been using Nvidia binary drivers and /tmp on a tmpfs for a long time, and it works perfectly; problem is probably on the mount parameters (avoid "nodev", "noexec", "nosuid", ... in /etc/fstab). Hope this helps.

                    We've been doing this since the beginning at Fuduntu, and recommended it for Eee PCs for years before that. It's about time others got on board.

                      KDE 4.x does.
