I've just finished setting up a Debian system running on an embedded device. It has custom partitioning, numerous config file changes, web content, and a couple of applications compiled from source.
This exact setup now needs mirroring to a dozen or so other identical embedded devices. They are all the same processor, memory, disk size etc (hence ”identical”). What would be the best way to do this?
The disks in the devices are not really physically accessible, otherwise my first though would have been to put a second disk in the finished box and dd to mirror it.
If I mirrored the disk to a USB stick, how would I get that onto the clean box? I guess it would depend on whether the BIOS could help?
