| # Why are we doing this? | |
| # | |
| # The hosted GitHub runners have free disk space split | |
| # between the root partition and a temporary partition, | |
| # leaving limited space for builds. We work around this | |
| # with easimon/maximize-build-space which creates a LVM | |
| # volume to combine the free space in both. | |
| # | |
| # We mount this new volume at /nix, and set TMPDIR so | |
| # all builds happen inside the volume. | |
