- Lots of .spec fixes from Mads Kiilerich:
Remove comment about update-grub - it isn't run in any scriptlets
patch info pages so they can be installed and removed correctly when renamed
fix references to grub/grub2 renames in info pages (#743964)
update README.Fedora (#734090)
fix comments for the hack for upgrading from grub2 < 1.99-4
fix sed syntax error preventing use of $RPM_OPT_FLAGS (#704820)
make /etc/grub2*.cfg %config(noreplace)
make grub.cfg %ghost - an empty file is of no use anyway
create /etc/default/grub more like anaconda would create it (#678453)
don't create rescue entries by default - grubby will not maintain them
anyway
set GRUB_SAVEDEFAULT=true so saved defaults works (rbhz#732058)
grub2-efi should have its own bash completion
don't set gfxpayload in efi mode - backport upstream r3402
- Handle dmraid better. Resolves: rhbz#742226
