grub2/0054-mkrescue-Check-xorriso-presence-before-doing-anythin.patch
Peter Jones 81987f4958 Update grub2 for f28
- Try to fix things for new compiler madness.
  I really don't know why gcc decided __attribute__((packed)) on a "typedef
  struct" should imply __attribute__((align (1))) and that it should have a
  warning that it does so.  The obvious behavior would be to keep the alignment
  of the first element unless it's used in another object or type that /also/
  hask the packed attribute.  Why should it change the default alignment at
  all?
- Merge in the BLS patches Javier and I wrote.
- Attempt to fix pmtimer initialization failures to not be super duper slow.

Subject: [PATCH 054/206] mkrescue: Check xorriso presence before doing
anything else.
mkrescue can't do anything useful without xorriso, so abort early if it's
not available.
