/sys: Network device status: link; Hard disks?

[Nico Schottelius]

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
