Its a good way to learn how different parts of Linux work
After you install arch a couple times you won’t be making posts asking why your grub is broken, youll already k ow how to fix it.
The last time my grub was broken was around 2012 when I ran Arch. After that I have rarely thought about grub at all.
I’d recommend something that guesses how to install grub onto your system correctly for beginners, and let them figure this stuff out when they’re used to basic Linux usage TBH
I had many problems with installing grub in a dual boot configuration, so much so that I moved to systemd-boot and never had problems after. I don’t know why, but it’s config file approach felt more intuitive.
I’m actually not sure why GRUB is such a popular boot loader that comes packaged with so many distros. Maybe GRUB does something more complex than just bootloading, but I don’t know if most users would care…
