And now you’re lost
Installing arch without archinstall is way too much fucking work. I’d much rather spend time fixing the 10% greater likelihood of encountering issues post install than doing all that fucking bullshit manually. The command line is better for a lot of things but configuring partitions and mount points is not one of them. I demand a fuckin gui for that stuff.
I’ve done it both by the book and arch install. Arch install is just nice.
The rationale in the OP is that with archinstall, an inexperienced user will have no idea where to even begin diagnosing any issues post install. Whereas installing manually is sort of a barrier to entry that ensures you know what you’re doing.
That’s a stupid reason to make an installation as painful as possible. I can follow the installation wiki but I just don’t have time for this. And an inexperienced user can follow the wiki or another how-to and finish the installation but still be lost if something breaks later on.
