Config woes

[marcbrevoort-cyberhive]

There appears to be something fundamental I'm missing on how the combi of fpm and pleaserun deals with (environment) configurations.

I have a sample config file in my .deb package which unpacks to /etc/default/packagename.example.

For this application, this can/should be manually edited and saved to /etc/default/packagename after which the service can be started and the config file is picked up.

However, when I (re)install the .deb package, /etc/default/packagename gets truncated to 0 bytes and the configuration is lost. Moreover, this truncating appears to happen BEFORE the --before-install script is run, thwarting my cunning plan to back it up before install and writing it back afterwards.

So I tried storing the confiuration in /etc/init.d/ instead, which doesn't get overwritten, but it also doesn't get picked up. What's the magic incantation that makes configurations be used and not overwritten each (re)install?

I have tried

• Specifying and not specifying --config-files
• enabling/disabling --deb-no-default-config-files flag
• specifying the whole dir /etc as config files (which would recursively set all files in there configuration)
• not having a --before-remove cleanup script

But the /etc/default/packagename file keeps getting overwritten. What else could be causing this behaviour?

Update: The "pleaserun" dir contains various 0-length files called /etc/default/packagename

-rw-rw-r-- 0/0               0 2022-06-24 09:59 ./usr/share/pleaserun/packagename/systemd/default/files/etc/default/packagename

Which turned out to be the culprit. Ideally these would not be generated at all, but for now I'm removing any files ending in /etc/default/packagename from the pleaserun directory and that stops pleaserun from killing my configurations.

Hmm… this does sound a bit odd. Can you show me your fpm command-line? I’ll see if I can reproduce this behavior with it.

the fpm command line creating these empty package files is

fpm -v $VERSIONREVISION -n ${PKGNAME} -s pleaserun -t dir "/usr/bin/${PKGNAME}"

and the above creates blank /etc/default/[packagename] files (unless fixed in the meantime).

The workaround I've had in place for some time is

find ${MYDIR}/${PKGNAME}.dir|grep /etc/default/${PKGNAME}$|xargs rm

As the /etc/default/[packagename] file is no longer present, it is no longer overwriting the existing one, which allows the settings of a previous version to be kept between installs. However it would be nicer if somehow these empty files simply weren't being generated.
