I'd like to suggest adding Lynx to the installer mainly as a convenience for initial file-management and configuration editing. I think it is lighter than mc, and has file-management features not seen in elinks.
I don't use Lynx so much for web-browsing, but for local file management, and it makes it much easier to bounce around all the configuration files to make sure you have them right before the first Crux reboot.
I love popd and pushd as much as anyone else, but Lynx has always stayed a favorite of mine.
Now jump back and forth:
g <arrow-up or arrow-down>
If you go straight to a directory, you'll get not only the ability to browse through the filesystem, but a very light file manager. You can get even more file management by using the "F"ull menu. If your editor environment is set, so much the better.
Go to the root directory to start browsing from:
or if already in lynx: g /
You can start in your home directory (or any directory really) the same way:
At any rate, it is easy to add lynx to your system after the fact, but I thought it might be a nice convenience keeping in the spirit of crux's light&simple approach without going overboard.
Just a thought anyway - even though I don't use it for much web-browsing, lynx is still my favorite lightweight file manager.
