Are Distribution Packages recommended nowadays?
The "Distribution Packages" page starts with the following sentence:
The OS-specific packages (eg. RPMs on Linux) are generally a better bet
than the vanilla .tar.bz2 binary bundles, because they will check for
dependencies and allow the package to be uninstalled at a later date.
While they may lag behind the latest GHC release, we recommend using
them anyway for the above reasons, unless you have a particular need for
new features or bug fixes.
Nowadays I think the idiomatic way to install GHC on linux is using GHCup. I've not seen using distribution packages recommended. Maybe this paragraph needs updating.
