[PATCH] services: Add fontconfig-file-system-service. |

Date: |
Wed, 18 Mar 2020 12:46:26 +0200 |
* gnu/services/desktop.scm (%fontconfig-file-system,
fontconfig-file-system-service): New variables.
(%desktop-services): Add fontconfig-file-system-service.
---
I've been using a tmpfs mounted read-only at /var/cache/fontconfig for
months now without any problems. This adds it to %desktop-services.
