Description Werner Sembach [TUXEDO] 2023-09-05 15:21:11 UTC

SUMMARY
Any plaintext file that starts with PACKAGE* and doesn't have a filename ending associated with a mime type, gets the mime type application/x-pak. This happens for example fore dkms.conf file that don't have licensing information preceding and therefore start with PACKAGE_NAME=<some_name>

STEPS TO REPRODUCE
echo "PACKAGEloremipsum" > foo

OBSERVED RESULT
foo has the mime type application/x-pak

EXPECTED RESULT
foo has the mime type text/plain

(available in About System)
KDE Plasma Version: 5.27.7
KDE Frameworks Version: 5.108.0

This would be a bug in the detection code upstream in shared-mime-info; please report it at https://gitlab.freedesktop.org/xdg/shared-mime-info/-/issues. Thanks!

That comes from the following entry in:

    /usr/share/mime/packages/freedesktop.org.xml

   <mime-type type="application/x-pak">
     <comment>PAK archive</comment>
      ...
     <comment xml:lang="en_GB">PAK archive</comment>
      ...
     <generic-icon name="package-x-generic"/>
     <magic priority="80">
       <match offset="0" type="string" value="PACK"/>
     </magic>
     <glob pattern="*.pak"/>
   </mime-type>

Looks like the "PAK Archive" format was something in DOS back in the 1990's. Can give you a German Wiki article (seemingly no English equivalent):

A propriatary ancient format with a far to generic magic value :/

I guess if someone sees this and still has such a file lying around let me know, maybe there are additional magic values that can be used.
