When the system boots, init(8) fires up a shell to execute the commands contained in (the real) /etc/rc. At boot only the root file system is mounted, thus you need a mechanism to mount /etc ahead of normal startup and pass whatever arguments the fake /etc/rc was invoked with on to the real /etc/rc. As long as no processes holds open any files within /etc and you don't need any of the files, /etc/{,s}pwd.db og /etc/group comes to mind, you should be able to unmount /etc at your own pace. I guess you should be in single user mode while doing this. Why do you need this strange detachment anyway? Backups?
