 Posted: Sun Oct 16, 2016 11:11 am Post subject: Forcing re-compile of initramfs? |
 |
|
How do I force a recompile of everything that goes into the initramfs (using genkernel-next)? Have have changed my system from an intel to amd cpu.
I recompiled @world and the kernel in advance, but forgot about the initramfs, so I'm getting a kernel panic. I managed to work around the issue by using another machine with less aggressive compiler flags to build the same kernel, but I'd like to fix it.
I've looked everywhere but I can't find where the files are cached.
Would it be considered a bug with genkernel that there is no command option to totally recreate the initramfs?
Thanks. |

Well it depends on whether you mean to rebuild the initramfs or recompile everything in it. Rebuilding it is a simple genkernel built-in command: | Code: | | genkernel initramfs |
but this doesn't rebuild the executables in the initramfs. Genkernel builds those but caches the binaries in /var/cache/genkernel. Erasing the contents of that directory (no need to erase its subdirectories) will force Genkernel to recompile them: | Code: | rm /var/cache/genekernel/*
genkernel initramfs |
@DONAHUE, --mrproper will not erase this cache and also causes the recompile of the whole kernel, something the OP didn't ask for.
