I set SCRIPTS_REMOTE_DIR to /tmp/one in oned.conf.
Drivers scripts are there but hooks ones are missing.
[CN]$ ll /tmp/one/
total 8
drwxr-xr-x 6 oneadmin cloud 4096 Aug 18 20:41 im
drwxr-xr-x 5 oneadmin cloud 4096 Aug 18 20:41 vmm

Should I provide more details?
I tried to mention them in my initial email of that thread [1].
