Hello Leo,
> This is new. I think the issue was introduced with recent work on (gnu > system image), perhaps from this commit: > > https://git.savannah.gnu.org/cgit/guix.git/commit/?id=da924796744bbb7b035a986fe5d28d8d613ff6af Before that commit "guix system vm" was always producing volatile images, regardless of the "--volatile" argument. The new behaviour is to only produce volatile images if "--volatile" is passed. This means that by default, "disk-image-rw" are created in /tmp so that QEMU can operate on RW images. The side effect is that those big images can fill /tmp pretty quickly as you noticed. We could use the ~/.cache/guix directory instead to store those images. We could also make "--volatile" the default and introduce a "--persistent" argument instead. That would restore the previous "guix system vm" behaviour. WDYT? Thanks, Mathieu
