I’m currently experimenting with Ubuntu Core and wanted to port my existing 18 image to 20. No I’m struggling with the grub configuration.
I need to add something to the kernel boot cmdline. With core18 I had the grub.cfg to do this. With core20 the grub.cfg is gone:
grub: boot configuration is shipped and managed by snapd
Unfortunately I’m unable to find any documentation on that topic? Hope someone can give me a hint.
Thanks, and btw: is this the right place to ask about Ubuntu Core? If so, maybe add a category?
