Cool.=20
Please excuse my ignorance but is there a way to get /boot/kernel.NAME =
installed without going via packages?
I am used to build and install by source. Thus I tried:
MWN> make KERNCONF=3D'GENERIC CUSTOM' DESTDIR=3D/tmp/NEW installkernel | =
& tee LOG
MWN> grep '^>>>' LOG
>>> Install check kernel started on Thu Oct 16 17:27:31 CEST 2025
>>> Installing kernel GENERIC on Thu Oct 16 17:27:31 CEST 2025
>>> Installing kernel GENERIC completed on Thu Oct 16 17:27:44 CEST 2025
>>> Install kernel(s) GENERIC completed in 13 seconds, ncpu: 16
MWN> ls -al /tmp/NEW/boot | grep kernel
drwxr-xr-x 2 root wheel 717 Oct 16 17:29 kernel
Only the first kernel found in KERNCONF will be installed, though.
Is there a way to end up in something like the following?=20
tmp/NEW/boot/kernel
tmp/NEW/boot/kernel.GENERIC
P.S. I tried make KERNCONF=3D'GENERIC CUSTOM' KERNEL=3D'GENERIC CUSTOM' =
DESTDIR=3D/tmp/NEW installkernel
same results as mentioned above
Regards,
Michael
