    These are virtual filesystems that provide a simple way to get info from
    the kernel using user-space tools. sysfs is new in 2.6-series kernels.

    These provide pseudo-terminals.

    This is used for shared memory. You can control the size of this by
    editing /etc/default/tmpfs.

    This is a virtual filesystem for providing information on currently attached
    usb devices.

    These are from udev.

    The tmpfs entry isn't needed (most programs don't use this shared memory),
    but you might as well leave it alone. The others are needed.

    See the man pages for 'proc', 'pts', and 'udev' - the others don't seem to
    have man pages. A Google search would likely turn up some info as well.
