Fedora "/tmp"

[Drew White]

Hi folks,

I want to increase the size of the tmpfs for the system, but I am unsure of how that would be done in Qubes so that it sticks.

I altered the FSTAB but it didn't keep the settings after reboot.

It's a standalone guest, it should be persistent.

What do I do please?

Hi Drew;
that's another one of the wonderfully undocumented effects of systemd.

Long story short: edit
/usr/lib/systemd/system/tmp.mount.d/30_qubes.conf, and set size=$manyG

Long story: systemd performs mounts with .mount unit files; by default,
if no "Options=" setting is specified, the parameters are read from
/etc/fstab like an old school distro.

But, if "Options=" is specified, those options are merged with the ones
in /etc/fstab. In the case of Qubes, these options are further
customized in the $name.mount.d/ directory; since those options do
specify the tmpfs size, this setting overrides the one set in /etc/fstab.

Thanks, that is very helpful!

Thanks a lot.
Just makes me want to get rid of SystemD even more now.

I'm working on it.. But without knowing the details I need to know it's hard to do what needs to be done to get it done. If that makes sense... any at all? ;}

I've had to increase this on past fedora qubes vms so long videos wouldn't time out. Never had an issue with debian though. And I haven't had the issue on fresh system with the latest fedora.
