mizdebsk added a new comment to an issue you are following:
An alternative to tmpfs would be adjusting virtual machine disk caching options, which I
suggested in the devel thread mentioned above. For builders that are virtual machines (and
most of them are), data written to guest virtual disk during mock build would actually be
kept in RAM - in host disk cache, and is written back to hardware disk in background, even
before vmhost runs out of memory.
