/tmp on Arch Linux

Arch linux はメモリーの半分の容量のスペースを tmp ファイルシステムとして /tmp にマウントする。例えば8GBのメモリを積んでいたら /tmp の容量はデフォルトで 4GB になる。試しに手元の環境で df コマンドを実行すると以下のような情報が得られた:

# df -h
Filesystem      Size  Used Avail Use% Mounted on
dev             3.9G     0  3.9G   0% /dev
run             3.9G  384K  3.9G   1% /run
/dev/sda 158G 8.0G 142G 6% /
