Yes, making it r/o except during system reconfiguration and package installation/upgrade is my definite goal. > /var is in principle not available during early boot > the drift of the hardware clock is updated at regular intervals and > cannot be on a read-only filesystem (but it is ok that we don't know > the drift at early boot (is this true?)) > we need to know whether or not the hardware clock is in utc during > early boot (is this actually required? if not, could someone point me > to a discussion/documentation?) Well, I think my personal opinion on this is that the way to keep the RTC accurate is called "NTP", not necessarily "/etc/adjtime" . Or to turn this around: if you really care about /etc/adjtime to keep the clock accurate, then make / r/w.
