This is a tricky subject. On some embedded systems it may be expected 
for a user or configuration utility to change some configs while not 
other configs. On some embedded systems it may be impossible (or 
unlikely) for the user to modify configurations.

When a package is upgraded sometimes new configuration options are added 
and sometimes they are deleted, sometimes the format of the 
configuration is changed entirely or moved to a different location. 
Other times the upgrade is just a maintenance release and only contains 
minor fixes.

If you mark a file as a config file by default opkg won't upgrade that 
file during a package upgrade, even if the user never made any 
modifications. At this point you are basically deciding to leave the 
original file unchanged and putting the burden of merging old and new 
config files on the user.

We've dealt with this by leaving install_alternative for all config 
files by default and only making custom rules with install_config for 
files we intend for users to change. For our device it makes sense for 
instance that a user may want to modify ntp.conf to add an ntp time 
source (we provide a web based utility to do this), yet it makes no 
sense for a user to change the dbus configuration. If during the course 
of a version upgrade a configuration option is renamed, eliminated or 
added, we provide a .postinstall script to modify the user configuration 
and make the required changes so the user doesn't end up with a broken 
device.

Ultimately I think a better frame work is needed to handle management of 
configs. Suppose your user wants to backup his device's configuration 
files to a PC. Then suppose said user's device is burnt to a crisp when 
lightning strikes an improperly arrested antenna (this has happened). He 
orders replacement but it arrives with new firmware. He sends his backed 
up config files to it from a and it doesn't work because the name of a 
setting in one of the config files changed.

Ideally you could provide a single script to migrate a config file from 
one package version to another. This script could be used when the 
package is upgraded OR when users send configuration files to the device.

Regards,
George McCollister

Exactly, and last time I checked opkg didn't have a way to forcefully
overwrite the old config file without prompting.

An idea I just had: maybe introduce a new install_* command. And then,
depending on an option in ptxconfig, install the file as a config file or
not. Also, you'll need to create individual patches for each package, and
the current patch contains far too many files that are certainly not meant
to be changed by the user.

I did not checked into opkg's code but there supposed to be a '-force-maintainer' option to do this. Otherwise the '-force-default' prevents prompting before leaving the file as is.

So, if opkg is run manually without arguments (apart the install or upgrade command), it will prompt before leaving a file as is and check with diff what has actually changed between the two versions.

The way it is does not prevent the maintainer to provide such a script on a config file. Actually, it is done like this on a debian distribution, isn't it ? I think that maybe a prerm script is then needed to check the validity of the current config file. If it has not changed, delete it and take the one in the package. If it is upgradable, perform the upgrade in a tmp config file and postinst script install this tmp config file back to its place.

I totally agree with that. We developed a script that records all needed configurations files at the same place as well as original configuration to be able to return to a known state (with the funny 'configator' nick name...)

We do have had issues with ipkg upgrade because it replaced the ipkg.conf config as well as the /etc/network/interfaces file. I would have preferred the upgrading process to stop instead of having all packages in their default configuration.

I have grepped all install_alternative in the rule directory and changing the ones I suppose should be install_config. It can be split into a big bunch of packages patches but I did not want to flood the ptxdist mailing list.
