There's been a periodic discussion of this issue in d-d. Note specifically: bootable CDROM distributions solve this problem by a number of means. One is to use a RAM filesystem for root, another is to use an immutable root but symlink /etc and parts of /dev elsewhere. The problem is addressable, but not entirely cleanly. Working implementations exist. Peace. -- Karsten M. Self <[EMAIL PROTECTED]> http://kmself.home.netcom.com/ What Part of "Gestalt" don't you understand?
