6 | # Simple script to generate a deb package for a Linux kernel. All the | |
4f66199b | 7 | # complexity of what to do with a kernel after it is installed or removed |
1da177e4 | 8 | # is left to other scripts and packages: they can install scripts in the |
fe233cb6 FP |
9 | # /etc/kernel/{pre,post}{inst,rm}.d/ directories (or an alternative location |
10 | # specified in KDEB_HOOKDIR) that will be called on package install and | |
11 | # removal. | |
