Users are looking for hardware information below /sysfs, not somewhere in /dev. /dev would actually be the last location I'd ever expect to provide hardware information. It also shouldn't be necessary to install a special tool to be able to parse hardware information. /dev/mdesc sounds like a relict from the old Linux days to me which should be superceded by sysfs. Wasn't it a goal to eventually move all system information to sysfs and even removing the remains from /proc in the distant future as /proc is actually the process filesystem and not for system information? > Also mdesc is root accessible only.

That's even worse. Users should be able to retrieve system information without being the root user. Adrian -- .''`.
