Subject: [PATCH] Revert "reopen SNP protocol for exclusive use by grub"
|
|
|
23d2ea |
|
|
|
23d2ea |
I *think* this should have been replaced by upstream's
|
|
|
23d2ea |
49426e9fd2e562c73a4f1206f32eff9e424a1a73, so I'm reverting for now.
|
|
|
23d2ea |
|
|
|
23d2ea |
May resolve rhbz#1273974.

This reverts commit 147daeab22db793978f952b6f0d832919a1b0081.
