Sent upstream: http://bugs.gw.com/view.php?id=430 This should be fixed by update to new version of file - file-5.24 in Rawhide. Feel free to reopen if it still doesn't work with file-5.24. |
Created attachment 991981 [details] Proposed fix Description of problem: Hybrid ISOs (those with El Torito boot image and also embedded MBR) are currently not distinguished from normal ISOs (without embedded MBR). It would be nice if they could be detected by file utility. Version-Release number of selected component (if applicable): file-5.22-1.fc23 How reproducible: Always Steps to Reproduce: 1. Download Fedora Workstation Live DVD 2. Run file on it Actual results: ISO 9660 CD-ROM filesystem data 'Fedora-Live-WS-x86_64-21-5' (bootable) Expected results: ISO 9660 CD-ROM filesystem data (DOS/MBR boot sector) 'Fedora-Live-WS-x86_64-21-5' (bootable) Additional info: Attached patch adds "(DOS/MBR boot sector)" to hybrid ISOs with embedded MBR. Feel free to change the string, I choose it to be compatible with strings used for MBR detection. To distinguish hybrid / non hybrid ISOs, one had to run 'file -l ISO' which was quite clumsy. This patch should ease the detection. Also please forward the patch to upstream.
