Folks, sorry to revive an old thread but for OpenBSD Routers in the Field (where power availability and graceful shutdown / restarts are far from guaranteed,
we have been using mfs mounted /var /dev and /tmp for years and it has been quite successful (a few hundred devices running for a few years) and only 1 or 2 failures (attributable to filesystem issues) in that time. however the impact of mfs (/var in particular) on upgrades has been quite painful, my latest iteration for fstab is to have / , /var /usr/local and /tmp with different mount points to support different mount options, (wxallowed for /usr/local) and to mfs mount /var/run, /var/logs /dev and /tmp #cat /etc/fstab ff0023511d131fc2.a / ffs rw,softdep,noatime 1 1 ff0023511d131fc2.b /usr/local ffs rw,wxallowed,nodev,softdep,noatime 1 2 ff0023511d131fc2.d /var ffs rw,nodev,nosuid,softdep,noatime 1 2 swap /tmp mfs rw,nosuid,noexec,nodev,-s=262144,-P=/persist-fs/tmp 0 0 swap /var/log mfs rw,nosuid,noexec,nodev,-s=524288,-P=/persist-fs/var/log 0 0 swap /var/run mfs rw,nosuid,noexec,nodev,-s=262144,-P=/persist-fs/var/run 0 0 swap /dev mfs rw,nosuid,noexec,-P=/persist-fs/dev,-i=2048,-s=32768 0 0 ################################################### This seems to solve problems with upgrades and package updates, I have left /var/www/logs/ out as we are not using httpd / webservices on the boxes in the field are there other directories that contain files that regularly change that should be mfs mounted ?
