Cool. 

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='GENERIC CUSTOM' DESTDIR=/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? 

tmp/NEW/boot/kernel
tmp/NEW/boot/kernel.GENERIC

P.S. I tried make KERNCONF='GENERIC CUSTOM' KERNEL='GENERIC CUSTOM' DESTDIR=/tmp/NEW installkernel
     same results as mentioned above
