| 7 | Subject: [PATCH 2/2] vt/conmakehash: improve reproducibility |
| 8 | |
| 9 | The file generated by conmakehash capture the application |
| 10 | path used to generate the file. While that can be informative, |
| 11 | it varies based on where the kernel was built, as the full |
| 12 | path is captured. |
| 13 | |
| 14 | We tweak the application to use a second input as the "capture |
| 15 | name", and then modify the Makefile to pass the basename of |
| 16 | the source, making it reproducible. |
| 17 | |
| 18 | This could be improved by using some sort of path mapping, |
| 19 | or the application manipualing argv[1] itself, but for now |
| 20 | this solves the reprodicibility issue. |
