> But for the one I'll have hanging in my office, I have loftier goals. With swap enabled, the kernel sources can actually be built right on-device. It will take some number of years. The partition where the kernel lives is /dev/pvd2 and is mounted under /boot. The device can build its own kernel from source, copy it to /boot/vmlinux, and reboot into it. If power is interrupted, thanks to ext4, it will reboot, recover the filesystem damage from the journal, and restart the compilation process. That is my plan, at least.
