grub_menuentry is broken in EL8 and Fedora 30+ #49

Closed trevor-vaughan closed 4 years ago

trevor-vaughan commented 4 years ago

EL8 and Fedora 30+ now use the blscfg module to load OS configurations from /boot/loader/entries. This means that we're going to have to fall back to grubby for systems that include this module in their /etc/grub2.cfg configuration until some method can be found to process this information without requiring grubby.

Perhaps parsing grubenv would help?

@jcpunk I'm actually working on that now. Luckily, the new rewrite of grubby is in BASH so I've been able to reverse engineer things.

Unfortunately, it's kind of a hot mess under the hood and we're going to have to support both BLS and old entries to make this thing make any kind of sense.

Also, updating the root disk seems to update it for all BLS entries (it just keeps getting more fun).
