As I wake up my wife complained that my laptop hadn't gone to sleep over night, so I glance at it before breakfast.
#Hypridle isn't running. Odd, all I've done recently to it is remove an u.used config...
Run it directly, it complains it can't find the config. Is it a homemanager symlink issue? Nope, it doesn't work on a copy either.
Touch a default config and run, it runs.
Empty file added to homemanager config and bug report filed, all before breakfast (at 10, but I slept in)
