(Already posted this to -questions, but got no comments at all!) In the interest of better support for diskless and in general for multiple installations, it seems to me that it would be nice if /etc were *not* on the same filesystem as root, but rather in /var or some other location, so that each machine can have its own copy. Unfortunately, "init" looks for "rc" in "/etc", so mounting a new filesystem on /etc would as a minimum make the original "/etc/rc" unreadable, making it very difficult to modify it. At the same time, people are probably too much used to the existence of "/etc/rc" to move it somewhere else. So, How about letting "init" look for "/rc" instead/before looking for /etc/rc ? This would help in having the following: 1) a main "rc" is called, which does the initial checks; 2) mounts the proper filesystem onto /etc; 3) passes control to /etc/rc With the current setting, the above might still work except that, once the new /etc is mounted, the original /etc/rc is no more readable.
