still excited about this one -- plan to add support to optimize zram parameters at some point to see if it's worthwhile to just always disable GC so long as there's RAM (or compressed RAM) available | 06:07:36 |

A string interpolates to itself.
A path in an interpolated expression is first copied into the Nix store, and the resulting string is the [store path] of the newly created store object .

 Gaétan Lepage | Yes, I know :/
I will try to identify the problematic test | 20:25:54 |

next step is to test whether disabling the problematic test helps I tried adding pytest-timeout and --timeout=100 and the test suit seems to pass just fine. | 12:14:05 |
| Gaétan Lepage | Without the need to disable any test. | 12:14:13 |
| Gaétan Lepage | I thought that pytest-timeout would fail a test that is taking too long | 12:14:35 |
