Since we have adopted grub as overlay package, two issues have come up:
- Grub-install and especially update-grub have gained a massive delay when used in chroot. In my tests it has been about 5-6 minutes, but other manjaro-architect users report Grub-install hanging for up to 20 minutes. Since grub is our default bootloader, this seems rather unfortunate issue.
- Grub in the repos doesn’t support zstd-compression, even though mainline grub already does.
Number 1 is more pressing of the issues. I haven’t seen any calamares reports about this, so it might not have hit the isos yet. Or, calamares might use some other type of grub installation process.
