The way I do it is cross-compiling everything needed on an ssh enabled
remote machine, and installing it into a folder on that machine with
On my arm machine then as root I do
"chflags -R noschg *"
"ssh user at host tar -cpf - /destdirfolder/* | tar -xpf - "
And voilà, world is installed.
I then copy the kernel from the obj dir to my boot partition via scp and
Usually this works.
