If you start with a read-only /, then no matter what you do, the first mount command will not be recorded in mtab (unless you implement a mount daemon that holds mtab in memory until it can write it somewhere). > Hrm, why don't we use /proc/mounts for mtab information, and have mount > store _only the extra information it needs_ in /var/run/mtab? What keeps you from implementing it? :-) A more technical problem: right now /etc/mtab presents a system-wide global view, but the contents of /proc/mounts is already a per-process thing. So if you want to use that, then you need a separate /var/run/mtab.<pid> for every process (or at least one mtab file per different namespace; which brings the question how do you detect if the process changes its namespace).
