[gentoo-dev] systems-246 changes tmpfs default size from 50% to 10% of RAM

[Zoltan Puskas]

Hi,

I've upgraded to and running systemd-246_rc2 on one of my systems and
noticed that tmpfs mounted directories are significantly smaller.

This is because with commit
https://github.com/systemd/systemd/commit/7d85383edbab73274dc81cc888d884bb01070bc2
they have changed them to be 10% of the physical memory instead of the
default of 50%.

This is a potentially breaking, or at least an unexpected behaviour
change, especially for people using tmpfs on /tmp for compiling.

Maybe we should make a news item to let people know that they either
need to add an fstab entry with size option set, or better, create a
systemd local override with relevant content.

Cheers,
Zoltan
