Hello community,
We recently moved MicroOS and Kubic to use tmpfs for /tmp instead of writing files there to disk.
This means files written to /tmp as never written to disk and so dissapear on reboot.
This was for a number of reasons, including
- Reducing wear on SSDs/SD card storage - Using less disk space and being more tidy generally - Being more like many other Distro's and Unixes including Debian, Arch, Fedora, Solaris, etc - Being more consistant with the FHS recommendations that /tmp is flushed on reboot https://www.pathname.com/fhs/pub/fhs-2.3.html#TMPTEMPORARYFILES
All of these reasons also apply for regular openSUSE, so I would like to propose that Tumbleweed moves to tmpfs for /tmp soon also.
The impact should be minimal, as all POSIX compliant applications should already assume that /tmp is not persistant between invocations of the program.
As we're walking paths that other distros long have, my own research suggests that vast majority of problematic /tmp use has already been resolved, such as by using /var/tmp instead.
We will likely impliment this as systemd mount unit, meaning if people disable it then they will be able to return to the old behaviour.
Does anyone have any objections, concerns, thoughts?
So hilariously, I thought we already did this, and the fact we didn't actually caused problems in user support in the Discord community. So this gets a HUGE +1 for me.
