even the root server has to do this ?? I thought the immutable flag
was only used in the vservers.

okay, i dont use it, as i consider disk space cheap, and
the extra trouble handling a unified file system just
add's even more against using it.
(then again, i'm only running vservers for myself, so i
only have a few vservers, not 49037823923 like an ISP
would have.
