[parted-devel] [PATCH 0/4] Add ability to set GPT PMBR boot flag

[bcl at redhat.com]

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.

  parted: print disk flags
  tests: update tests for new disk flags output
  tests: add test for GPT PMBR legacy_boot flag
