RB Linux is an embedded mini-distribution I put together while working with Wafer 4823, a single board computer originally shipped with FreeDOS.
Embedded systems running this distribution operate three automated parking lots in Bratislava, Slovakia and half a dozen energy consumption monitoring and controlling systems in industry companies around Slovakia. Enhanced with
iptables, RB Linux had been used for years in our appartment's router machine.
RB Linux consists of the following software components (most of them are optional):
RB Linux fits on a single 1.44 MB floppy disk, from which it can both boot and be installed on the HDD. As far as I can remember, when running, requires no more than 4MB RAM, installation does not require more than 4MB of hard disk space.
RB Linux is actually not much of a Linux distribution, it's just a fat, hairy shell script that does a few things:
makedist script depends on the host system's
mkinitrd program. On recent version of a desktop distribution, the init ramdisk might get a bit bigger than the one we would have created ourselves. TODO!
