reduce swappiness in /proc/sys/vm/swappiness.There are some additional tricks to check: Use lsof to find processes blocking the readonly mount. Passwd, shadow – may be modified by user interactionĪpt-get could be modified to remount before installing anything: DPkg nf – no problem with static nameserver configurations Nologin – This should already be a symlink to /var/lib/initscripts/nologin Network/run – ifupdown links /etc/network/run to /dev/shm/network in postinst if /dev/shm exists and /etc/network/run does not my installation was not successful without an existing network/run/ifstates, so I copied the complete directory once the network was up and running. Mtab – Create a symlink from /etc/mtab to /proc/self/mounts We need to take care about /etc as there are some files which need special preparation:Īdjtime – should be linked to somewhere beyond /var /etc/init.d/hwclockfirst.sh and hwclock.sh should be adjusted to show the option –noadjtimeīlkid.tab – should be linked to somewhere beyond /var the environement variable BLKID_FILE must be set to /var/local/blkid.tab in /etc/environment var as exteneded fs mounted read writableĪnd now to the tricks. There are already some special file systems available in a standard linux installation, so we do not need to take care about: Everything below /var is assumed of being accessible as it makes no sense from my point of view to restrict access for everything, which could nevertheless also be achieved by following this instructions. So here is a list of files to take care of. To create a read only root file system we need to know which processes access which files and which files must be accessible.
