Hi Brad, all!

Before I even try to submit any changes directly to CONTRIBUTING.md, I'd =
like to discuss it here.

What I'm facing is the need to create Release Notes from time to time. Th=
ose Release Notes are for server admins, not for openbmc developers. The =
most difficult and time consuming parts about this effort are:

1. Figuring out the end user impact
2. Figuring out what changes have been brought in by "bump version" commi=
ts

Thankfully, for linux-obmc version bumps Patrick Williams and Joel Stanle=
y do a great job by including the 'git shortlog' output. Unfortunately, n=
ot everyone is following this rule for bumps. I'd really like this to bec=
ome a requirement for 'bump version' commits. They could then be parsed a=
utomatically. It would also be helpful if=C2=A0 the synopsis included the=
 old and the new hash, e.g.:

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
some-package: bump version 62286ef3 to 4fa63380

Author Name (2):
=C2=A0 commit 1 synopsis
=C2=A0 another commit synopsis

Another Author (3):
=C2=A0 great commit
=C2=A0 yet another great commit
=C2=A0 fix previous not-so-great commit=C2=A0

Change-Id: some-long-gerrit-hash
Signed-off-by: The Version Bumper <bumper@nowhere.net>
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Including the component's origin git URL could also be helpful for automa=
ting change log fetching (finding that in the recipe is sometimes a non-t=
rivial task for a script).

Now for item 1, it would be great if we could have a mandatory "End-user-=
impact" line/section, like these added to the following real commits:

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
whitelist: Add new phosphor settings directories
=C2=A0=C2=A0 =C2=A0
The phosphor settings properties used to be stored under
/var/lib/obmc/ but they have moved to /var/lib/phosphor-*
directories.
=C2=A0=C2=A0 =C2=A0
Update the code update whitelist to include these
directories so that the settings properties and inventory
are preserved across code updates.
=C2=A0=C2=A0 =C2=A0
Closes openbmc/openbmc#3346
=C2=A0=C2=A0 =C2=A0
Tested: On Zaius, a PrepareForUpdate and an Apply preserve
the settings.

End-user-impact: None =C2=A0=C2=A0

or:

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Fix to speed up boot to BMC Ready state
=C2=A0=C2=A0=C2=A0
The legacy services(like system and chassis) was assigned nice value
of 19 to alleviate CPU stress at boot time. The systemd bootchart
showed that many services are dependedent on the system service. The
nice is set to default value of 0 and there is a consistent improvement
of ~10 sec in BMC getting to ready state.

What do you think? Is this feasible? Any other ideas how we could simplif=
y creating release notes suitable for end users?

I totally understand that for the openbmc project the end users are syste=
m vendors, but for them (us) the end users are the server admins, and pro=
viding them with usable release notes is crucial. I'm quite sure that thi=
s is a kind of task that all vendors face, not just YADRO.

Alexander.
