This patchset introduces /run into mkinitcpio. The size and mode options of the tmpfs should be the same in mkinitcpio and initscripts. Please comment.

Hello,
I don't run understand why there is a need for /run in mkinitcpio. Shouldn't this be in /etc/fstab like any other userland filesystem?

as of udev 167, udev's database will use /run/udev if its available.

Programs that run in early userspace can leave permanent information behind, like udev, mdadm. I don't know if this is very helpful right now, but if I understand this right, it will become de-facto standard.
