grub2/grub2-pass-corret-root-for-nfsroot.patch
Stephan Kulow c4bfec4a4c Accepting request 212884 from Base:System
I think it is good time to update to 2.02 so it can get more testing.
Although internal changes are pretty extensive, externally it should be
pretty much the same. The main user visible changes are

 - autogen is not used anymore, so we can finally simplify patches
   and recreate files during RPM build. So generated files need not be
   patched and shipped any more.

 - GRUB_HIDDEN_TIMEOUT is deprecated, we should use GRUB_TIMEOUT_STYLE
   instead. This will need perl-Bootloader and YaST changes. Old config
   is still accpepted so nothing should be broken.

 - native pvgrub2 support for Xen PV guests.

 - ARM support (32 and 64 bit), although it has rough edges. (forwarded request 212604 from arvidjaar)

Subject: [PATCH] Pass corret root= for nfsroot
References: bnc#774548
Patch-Mainline: no
Fix / is mounted on nfs. The fix is to pass kernel parameters
with correct root= for nfs. However since grub2 doesn't support
nfs file system module, the /boot on nfs is not possible and
grub2-probe not work in probing nfs mounted path. The fix is merely
on the script level and not use grub2-probe for above reasons.
