Hi all,
this is a announcement regarding changes which have just landed in upstream systemd (not yet released nor pushed to Factory) regarding /media and /tmp: - /media will no longer mounted as tmpfs. This is because udisks2 will no longer use /media for mounting removables devices okay so all work and effort to fix situation comparing 11.4 and 12.1 is lost (again :-() but /run/media/<user> Sometimes (old song) they should really think about that not all computers are phone device. We will adapt again to survive - /var/run and /var/lock are no longer bind-mounted to /run | /run/lock. How much package will have to be fixed again just for that ? We should replace those directories with symlink to /run | /run/lock (probably at initrd time, this is what is done on Fedora) Could it be pushed before M3 please to have a better timeframe for feedback and tests? - /tmp is mounted as tmpfs, to make the default setups as stateless as possible. As stated on https://fedoraproject.org/wiki/Features/tmp-on-tmpfs , we might need to fix some applications to use /var/tmp instead of /tmp when they need persistent storage. Another big issue is educating users. Just have a clear listing of all application that need to be fixed and all kind of usage verified, like split tar gimp inkscape (memory hungry things) etc and all kind of stuff that could use /tmp There's a bunch of application that use it to swap undo and kind of things using tmpfs could be pretty counter intuitive So test and bench need to be written for openQA
the whole /etc/sysconfig/cron has to be revisited completely And a point that need to be clear and have a hook permitting users to clean it up What happens with my old /tmp directory as soon as this feature is enabled? On the next boot we'll simply mount the directory over with a tmpfs. and then you keep forever the 4GB iso you put it inside before the update/upgrade -> move previous /tmp to /tmp.old or rpmsave or whatever than joe and jane can cleanup
Thanks for the RFC Fredirc :D
