Subject: [PATCH] Swap over to dirfd+basename based operation within the fsm
Florian Festi 94360a
Florian Festi 94360a
Within fsm this is just a matter of adjusting error messages to include
Florian Festi 94360a
the directory... if it only wasn't for the plugins requiring absolute
Florian Festi 94360a
paths for outside users. For the plugins, we need to assemble absolute
Florian Festi 94360a
paths as needed, both in ensureDir() and plugin file slots.
