Yesterday's next was good.

Last commit that changed symlink.c was

commit d7866652cda316006089fa42b931627992c08010
sysfs: Don't allow the creation of symlinks we can't remove

This commit added the above WARN() message. I haven't tried to revert
this commit to check if that helps with qeth initialization.
