Hi adr, Liam provided valuable feedback in both reviews, and if anything we haven't put enough effort into smoothing out the rough edges Liam pointed out, like figuring out why command-line editing and PATH weren't set up right out of the box. There's always room for improvement, and our documentation is sometimes hard to follow, missing parts, or too wordy in places.
This feedback helps us to improve the out-of-the-box experience for users, fix unnecessarily confusing parts of the experience, and identify where the documentation is lacking or hard to find. Gatekeeping NetBSD on the basis of prior expertise is not good for the community, and not good for the project. sysinst is supposed to be a tool to help you, not a test of your patience or knowledge. We would appreciate it if you toned down your criticism of a new user and their honest feedback about the experience so we as a community don't discourage other users and further feedback as we continue to improve NetBSD. Thanks, -Riastradh, NetBSD core team
