- Do not use libsysfs
It makes assumptions about sysfs which are not true. Its API does not
offer any abstraction, it exposes all the kernel driver-core
implementation details in its own API. Therefore it is not better than
reading directories and opening the files yourself.
Also, it is not actively maintained, in the sense of reflecting the
current kernel-development. The goal of providing a stable interface
to sysfs has failed, it causes more problems, than it solves. It
violates many of the rules in this document.

The problem is that even on there are packages like pcmciautils that still link to libsysfs and contain things like #define PATH_TO_SOCKET "/sys/class/pcmcia_socket/". Are they expected to be fixed?
