Some BIOS systems refuse to boot from GPT disks unless the boot flag of the PMBR has been set. Matthew Garrett has written a patch to add a disk_set command and a legacy_boot flag for the disk. I have added display of the disk flags using a new output line, like so:
Model: (file) Disk /home/bcl/disk.img: 4295MB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: legacy_boot Number Start End Size File system Name Flags 1 1049kB 99.6MB 98.6MB bootstuff Or in machine mode: BYT; /home/bcl/disk.img:4295MB:file:512:512:gpt::legacy_boot; 1:1049kB:99.6MB:98.6MB::bootstuff:; I have also updated existing tests so that they work properly with the new output format as well as added a new test (t0208-gpt-legacy_boot.sh) I am interested in feedback in this change, I am planning on adding it to Fedora's rawhide release unless I hear any compelling objections or other solutions for displaying the disk flags. I expect that it will break things that expect precise output from parted instead of parsing out what they need, but I think this method is the least disruptive. Brian C.
