Re: Utility to list /dev/nodes & serno's

Sascha,

Did you wish something like attached perl script?

It is a quick and dirty hack for my needs (improved after sysctl was mentioned here).

Using this mechanism you can export other kinds of information as well

manually running udevd in single user mode is such a big deal (you could
even autostart it. You're root in single user mode). The script is also
less robust wrt hotplug events that move disks around (this isn't
realistic with physical swapping of disks, but might be an issue with
network storage).

Well, I thought we're talking about a simple utility to help the user find the corresponding /dev/serno/... for e.g. a /dev/da... node and not about some full fledged disk attribute dumping utility (which tuxillo's doesn't seem to be). If that is what's wanted here, we should use a different name at least (devattr(8) perhaps? any other ideas?) and view the serno information as a first feature with more to come.
