Description Robert Yang 2015-09-17 06:44:48 UTC 
Different layers may set the same target's ALTERNATIVE_PRIORITY as the same, this would cause undetermined build results. we can check and warn this.
Comment 1 Richard Purdie 2015-09-17 15:02:46 UTC 
Not sure if we can actualy easily check for this since there is no central location of this data and recipes can't inspect each other's state.
Comment 2 Chen Qi 2016-11-15 06:46:36 UTC 
I think the only way we could do this is in the update-alternative script itself.
When the script runs to change the database, it could do this extra checking and warn users if it finds the same priority.

    package_manager: default to have scriptlet output captured in log
    
    We need to have scriptlet output captured in log. If we don't do so,
    some useful information from scriptlets (especially postinstall script)
    would be missing. In case a script has a warning message but it does not
    necessarily have to fail, the message should be captured.
    
    Opkg has already done that. Change for rpm and dpkg so that scriptlet
    output is captured and no warning message is missing.

The rest part is to bump opkg-utils' rev to "1a708fd73d10c2b7677dd4cc4e017746ebbb9166" which could check priority conflicts.
