Hi,
Why not create some useful overlays like "kernel-headers", "compiler environment" or similar?
For sure, I can do "apt-get" for several packages, but I prefer to have these on the media without use the network (and without remastering, like do puppyLinux).
Also, I suggest to support kernel-headers-***-finnix on the repository, because is very hard to compile new kernel modules (apt-get only finds the full kernel source)
Thank you!
