Sorry for my english.
Change the location in
/etc/pacman.conf? Can be replaced in
tmpfs /tmp tmpfs nodev,nosuid 0 0
#tmpfs /tmp tmpfs nodev,nosuid 0 0
/etc/yaourtrc - TMPDIR="/tmp?
Yes you are correct, it should be /etc/yaourtrc, I was typing too quickly and it somehow came out pacman.conf &_&. Thanks for pointing that out, I have changed it already :) ~Zeroedout
