Hi, Am I right that you feel that this should be documented?

lock_path is config option for oslo_concurency, the config help for the option:
"Directory to use for lock files. For security, the specified directory should only be writable by the user running the processes that need locking. Defaults to environment variable OSLO_LOCK_PATH. If external locks are used, a lock path must be set. (string value)"

Changed in neutron:
status:	New → Confirmed
importance:	Undecided → Low

From other perspective oslo.concurrency's lock_path config option should default to something like /var/lock instead of OSLO_LOCK_PATH environment variable

I added the option for all related docs (Suse, rdo, Ubuntu compute/controller) so now I think it will be consistent for all:
