Hello everybody!
Will /sys provide details about link status of network cards
and can I also find out what devices are harddisks?
Like having /sys/block/hda/type, which contains "cd-rom" or
"harddisk" or similar.
Or having something like /sys/class/net/eth0/link with 0/1 setting?
I know some or all information can be retrieved somehow differnt
(like using /proc), but shouldn't those be found in /sys?
Just some question on how we can use /sys useful.
Greetings,
Nico

Hmm, sounds nice to me. I don't know if something like
/sys/class/net/eth0/link as you describe it would be accepted, but I've
been wanting to play with sysfs for a while and this sounds like a nice
and resonably simple little project, I will take a shot at trying to
implement that.

Perhaps there is a even a default method for network
device drivers to show their link status, but I don't know where
and having it in /sys seems senseful to me.
Anyway, is this the wrong list to ask questions about /sys or
where can I find information about what the sense of /sys is and
what it should and will contain?

Nico

You probably just want to expose the state of netif_carrier_ok (and netif_running).
Doing it in net-sysfs.c is trivial. I was hoping someone else would learn something
and do it for me.

That is exactely what I've started to do, but it's taking me a little
while since I have limited time and have to learn about sysfs first. But
it's a nice learning experience and I'll post a patch as soon as I have
something that works resonably, but it might take me a few days.
