[gentoo-user] emerge custom notes reminders

[gentoo-user] emerge custom notes reminders

[thelma]

Is there a way to add custom notes reminders during emerge or after?

I've upgraded the bin scanner package (from overlay):
brother-scan4-bin-0.4.4-r4
and I receive an email note from emerge:
----
LOG: postinst
You may need to be in the scanner or plugdev group in order to use the
scanner
To add a network scanner to sane, run:
brsaneconfig4 -a name=(name your device) model=(model name) ip=xx.xx.xx.xx
or simply run brsaneconfig4 for more options
----

I didn't pay attention to it as my scanner was already configured.
What it didn't tell me that the upgrade emptied my configuration file:
/opt/brother/scanner/brscan4/brsanenetdevice4.cfg

It is not a Gentoo like behaviour.  If there are any changes need to be
made it should be done via: cfgupdate etc. style;  not just wipe the
configuration file.

It was overwritten because that directory is not part of CONFIG_PROTECT,
hardly surprising as that is not a standard configuration location. If
the device can't be configured from a file in /etc the ebuild needs to
back up the configuration before installing the new version, so file a
bug with the overlay.

Couldn't that location be added in make.conf?  As you pointed out, it
shouldn't be there but since it is, maybe protection can be added to
prevent future issues.

I imagine that would prevent the new driver being installed too. The
problem appears to stem from having the binary and configuration file in
the same directory.

I've already notified Chris gentoo@wintermoon.de (I think he maintains it).

Is it possible to protect a single file via make.conf ?
/opt/brother/scanner/brscan4/brsanenetdevice4.cfg

Then there is that.  One would think the config file would be in /etc
for a printer/scanner.  As you pointed out, that is the logical place
for it to go.  I wonder, does the software even look in /etc first and
then in /opt/***?  For example, on first use of KDE, it reads a default
file from /usr somewhere and then copies that to the users home
directory.  Maybe the driver should or can do that with /etc, instead of
/home of course.  In other words, take the file from /opt and stick it
somewhere in /etc that it looks for it and is protected in the future. 

Just thinking out loud to see if something pokes a fix that doesn't come
back to bite later.  ;-)

man make.conf says yes.

Here is a link to this ebuild:
https://github.com/stefan-langenmaier/brother-overlay/blob/master/media-gfx/brother-scan4-bin/brother-scan4-bin-0.4.4-r4.ebuild

The installation is done via rpm, that is why.

What kind of reminders? Perhaps we could have a developer add some
encouraging messages to various packages, or maybe some news items? I
know I could use some encouragement.

I could keep packages in an overlay and write messages to myself, but
I'm not sure it'd work as well.

Yes, it worked:
CONFIG_PROTECT="/opt/brother/scanner/brscan4/brsanenetdevice4.cfg"

after emerging I got a message:
 * IMPORTANT: config file '/opt/brother/scanner/brscan4/brsanenetdevice4.cfg' needs updating.

At least you found a workaround.  Still, one would think it would be in
/etc.  That tends to be the Linux way of things.  At least you found a
solution that prevents it from overwriting your config file.  Hopefully
they won't rename the file now.  ;-)

A simple additional post installation note:

WARNING: configuration file was wiped out.
run again:
brsaneconfig4 -a name=(name your device) model=(model name) ip=xx.xx.xx.xx

add/or note:
add to make.conf
CONFIG_PROTECT="/opt/brother/scanner/brscan4/brsanenetdevice4.cfg"

Would do the trick.

You can add functions to ebuilds in /etc/portage/env/cat/pkg, something
like

post_pkg_postinst() {
	elog "Say goodbye to your config file!"
}

Good one, I like it. Will suggest it to the developer :-/
