realinkat() returns EINVAL when invoked on a non-symlinks. It's not a
real error, just a way to report that mismatch.

Not sure what else I can suggest then, except attaching gdb to logind
and check what happens when you switch VTs... it should be sufficient
to set a breakpoint onto devnode_acl_all() and wait until it gets
triggered, and then follow the code until you see EINVAL thrown.

Unless you know gdb well enough you shouldn't attempt that though...
