Subject: Use tmpfs to mount /tmp
X-Git-Url: http://gitweb.hugovil.com/?a=commitdiff_plain;h=1083076034a8c41028e0587f302bfc8cfdb776af;p=hvlinux.git

Use tmpfs to mount /tmp

Add optional size for /tmp partition. By default, tmpfs will reserve up to half
the RAM for any tmpfs filesystem without a specific size.
