Different filesystems, crypto, boot order details, etc. It was a pita to maintain two similar things with different enough details :( this starts to move back to that, and I'm not sure that is a good idea. It seemed like the right choice, but maybe we could consider taking another look at that... when it first arrived, boot1.efi could easily fit the install once and forget forever. As the features grew, that assumption changed. This is why I'm putting together a design doc. There is no easy button here. I thought it was no brainer yes to drop it and just use loader.efi, but as things get more complicated I've become less sure... Warner > -- > > Rebecca Cran > >
