Bug#865450: systemd: tmpfs size mount option ignored when expressed in %

[Jacek Politowski]

Package: systemd
Version: 233-9
Severity: important

Dear Maintainer,

I believe the bug #851492 should be reopened since there seems to be a
regression after last upgrade and fix introduced in 232-11 doesn't work
anymore.

I've upgraded systemd (232-25 -> 233-9) and on next reboot my tmpfs on /tmp was
4K in size (which led for example to gdm3 not being able to display the greeter).

I have 'Options=mode=1777,strictatime,size=70%' in /etc/systemd/system/tmp.mount

Remount with:
# mount -o remount,size=70% /tmp
fixes the issue.
(At least after previous remount to fixed size with
# mount -o remount,size=4G /tmp)

Also changing /etc/systemd/system/tmp.mount to fixed size=4G solves the issue
after the reboot.

Best regards,
Jacek Politowski
