In Ubuntu the permissions for the /sys filesystem are much more lax than on a default Debian install. If I have a program trying to access /sys/class/net/eth0 on Ubuntu there is no issue, but in Debian the permissions are locked down.
I understand now that /sys is created as a virtual space for querying/updating kernel values, but I can't figure out how to modify the permissions that /sys gets created with. Is it a configuration option when compiling the kernel? Can it be modified with tools like sysfsutils?
Edit: I have realized that my installation of Debian might have been modified from the server host I am using. Any ideas on how they modified the permissions of the directory?
