How is it enabled in a vanilla kernel?

Yup.... mine is stock from kernel.org

I don't recall seeing any option for loginuid.

What module is it?  I probably don't have it mounted.

Thanks for getting back.
I don't know why getlogin() is using /proc/self/loginuid on openSUSE,
and why their kernels provide that file while a vanilla kernel does not.
I think this issue should be discussed downstreams.
Anyway, as this is clearly not an issue with logname(1) and how it
uses getlogin(), I'm marking this as not a bug.

Have a nice day,
