You can join Fedora infra to change it :) Nowadays, you can mount /var/lib/mock on zram, too: $ cat /etc/systemd/zram-generator.conf [zram0] zram-fraction = 0.5 max-zram-size = 4096 [zram1] mount-point = /var/lib/mock zram-fraction = 0.75 max-zram-size = 12288 Regards, Dominik -- Fedora https://getfedora.org | RPM Fusion http://rpmfusion.org There should be a science of discontent.
