question about tmpfs

[Styopa Semenukha]

Hi,

This is probably not related to Nginx, you might want to visit Linux forums or lists for more detailed information. However, having tmpfs mounted at those directories is a normal mode of operation in many Linux distros. They are mounted automatically, and typically you don't need to worry about them.

I recommend reading at least the section about tmpfs in mount(8) manual page:
http://linux.die.net/man/8/mount
