[Buildroot] [PATCH 0/2] Manual updates

[Fiona Klute via buildroot]

From: "Fiona Klute (WIWA)" <fiona.klute@gmx.de>

These two patches integrate points that Arnout Vandecappelle clarified
on the mailing list in replies to me into the manual. I hope I didn't
add any errors in rephrasing them, please let me know if anything
needs to be changed.

Best regards,
Fiona

[Buildroot] [PATCH 1/2] docs/manual: describe relying on default options

[Fiona Klute via buildroot]

From: "Fiona Klute (WIWA)" <fiona.klute@gmx.de>

People can assume that e.g. Busybox options enabled in the package are
enabled when writing code for Buildroot. Anyone who uses custom
configurations that disable default options needs to make sure
relevant scripts etc. still work for themselves.

I understand the wish to document this, but I'm not sure an
"Integration principles" is the right place. Shouldn't we document that
in a section where we document the expectations in terms of init
scripts instead?

Arnout explicitly requested I put it there in this mail:
https://lore.kernel.org/buildroot/6d02d2d5-e71e-45b3-a447-e81521085e7a@mind.be/

I'm happy to respin and put it elsewhere, but I'd like to avoid a back
and forth between two maintainers telling me different things, so I'd
appreciate if you could find an agreement before I do.

Best regards,
Fiona

Ah crap :-)

You're absolutely right obviously.

I don't have a strong opinion, but I think
section https://buildroot.org/downloads/manual/manual.html#adding-packages-start-script
makes more sense, as it's actually close to where it matters. Arnout?

  The init scripts are just an example here, the principle applies more in 
general. It also applies to e.g. ifupdown scripts, or even systemd unit files 
(e.g. if a systemd unit file needs some ExecStartPre command). That's why I 
thought that the start script was not the most appropriate place.

  Regards,
  Arnout

ACK. But then perhaps the discussion can be extended beyond Busybox.
For example for uClibc-ng, we also assume it is built with our default
configuration, and don't try to support the myriad of possible
uClibc-ng configurations.

I've tried to make clearer that it's a general thing, with Busybox being
an example (patch 1 in the "Update init script style" series I just
sent). I hope that works.

Best regards,
Fiona
