https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=249192 Bug ID: 249192 Summary: /etc/rc changes to support new rcorder -p option for parallel startup. Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: conf Assignee: bugs@FreeBSD.org Reporter: unitrunker@gmail.com This will be a patch to /etc/rc to optionally turn on the new '-p' option to run rc scripts in parallel. See: https://reviews.freebsd.org/D25389 /etc/rc currently does not support output from 'rcorder -p'. Make parallel startup optional by an entry in /etc/rc.conf: rc_parallel_start="YES" This name mirrors the current, existing variable "jail_parallel_start" that allows jails to start up in parallel. See rc.conf(5). Acceptance criteria 1: rc_parallel_start="YES" causes /etc/rc to pass '-p' option to rcorder in the early and late passes. An rc_parallel_start that is undefined, "NO" or any value other than "YES" (using checkyesno) will cause /etc/rc to omit the '-p' option to rcorder. Acceptance criteria 2: If rcorder returns multiple script paths per line separated by a space, /etc/rc will execute each script - with each script path passed to run_sc_script - as a background task. This behavior is independent of the rc_parallel_start option. Acceptance criteria 3: After processing each line of output from rcorder, /etc/rc will pause by calling 'wait' to allow all rc script tasks to complete before proceeding to the next line of output from rcorder. This behavior is independent of the rc_parallel_start option. Note: in the future, parallel start-up may become the default. This does not eliminate the need for the rc_parallel_start variable. Supporting rc_parallel_start="NO" in /etc/rc.conf will remain useful for debugging rc scripts. Patch as attachment is forthcoming. Similar changes to /etc/rc.suspend and /etc/rc.resume are out-of-scope. Patches will be submitted separately. -- You are receiving this mail because: You are the assignee for the bug.help
