The handbook steps for setting up genkernel are [1]: # emerge gentoo-sources genkernel # genkernel --menuconfig all # optional # genkernel all If you stay conservative (e.g. ext2/3 boot partition), there's no need for the menuconfig step. However, when I try and build a stage4 using: # cat default-stage4-i686-2013.1.spec … boot/kernel: gentoo boot/kernel/gentoo/sources: gentoo-sources # catalyst -f spec/default-stage4-i686-2013.1.spec I get: /proc is still mounted; performing auto-bind-umount... Auto-unbind successful... Traceback (most recent call last): File "/usr/lib/catalyst/catalyst", line 214, in build_target mytarget.run() File "modules/generic_stage_target.py", line 1290, in run apply(getattr(self,x)) File "modules/generic_stage_target.py", line 1420, in build_kernel if not os.path.exists(self.settings["boot/kernel/"+kname+"/config"]): KeyError: 'boot/kernel/gentoo/config' !!! catalyst: Error encountered during run of target stage4 What's changed? Why do I need to seed catalyst with a config file, when I don't need to from the handbook instructions? Maybe this usage is just unimplemented because nobody has needed it yet?
