[arch-general] file-5.14 - change in how information is read from vmlinuz?
Hi, I previously used the output from `file /boot/*` on the various vmlinuz files in /boot/* to detect what kernels were installed on a machine. As of file 5.14 this no longer works[1]. I'm not sure what's changed, perhaps the magic.mgc file? When I copy the magic.mgc file from previous (5.13) version of the file package I get the 'expected' output[2]. Not sure if this is a bug or simply a change in behaviour.

file -k gives better results[1]. I believe that happens because “x86 boot sector” has a higher priority or something like that in the new version.

Thanks, so its a priority thing in the magic.mgc I guess. On Tue, Apr 2, 2013 at 11:06 PM, Chris “Kwpolska” Warrick <kwpolska@gmail.com> wrote:

This is useful, should prevent such a 'bug' regarding priority ever affecting my script again, thanks =)
