Summary and Info:
I've been experimenting with basic arch package support in libdnf[1].
Yes, it's primarily built for managing RPMs, but since libsolv[2] has some arch support already,
I was thinking that having support for loading and querying arch repos would be nice.

As part of that, I'd like to run makepkg during the build process to generate test data from source.
These are usually empty packages with minimal dependencies - and they're completely under my control (no untrusted sources).
Since I've been using containers during development a lot,
I frequently face a situation that makepkg cannot be executed, because of running under root.
Back in 2014 when --asroot option was removed, containers weren't used that frequently
and that makes me think, if you wouldn't reconsider the decision and bring it back (probably in a different form).

How about setting an env variable, e.g. DANGEROUS_MAKEPKG_ALLOW_ROOT=1 ?

Steps to Reproduce:
$ podman run -it archlinux:latest
[root@3b23534af88f /]# makepkg
==> ERROR: Running makepkg as root is not allowed as it can cause permanent,
catastrophic damage to your system.
