Here goes my judging a book by its cover
Congratulations on using the correct spelling for endeavour.
-> It also bundles yay to easily fetch packages from the Arch User Repository, AUR. The yay command takes the same switches as pacman does,
If ever two apps deserved to be merged it is pacman and yay. It's like having /bin/ls and /bin/ls-etc which is a wrapper around /bin/ls to look in /etc. And the name... it's as unintuitive as it gets. Even "yarp" in Hot Fuzz was understandable and derivable to "narp".
-> When you run the installation program, it asks which of its two modes to use: offline or online.
This is a good feature, because I have seen more than one Linux installation get their over inflated knickers in a twist when it "thinks" the network is there but is not. Asking do you want offline or online yields a definite answer.
-> Xfce, KDE Plasma, GNOME, MATE, Cinnamon, Budgie, LXQt, LXDE, and the i3 tiling window manager....
-> Impressively, there are Community Editions with even more choices, with options for OpenBox, Deepin, and additional tiling environments: Sway, BSPWM, Qtile, LeftWM, and the homegrown WORM.
That's a heck of a lot of desktops. Despite my usual reservations about seemingly endless distros (and umpteen choices even within those distros) I'm glad to see that WORM gets a mention. It's very minimalist for those who like that sort of thing.
-> The distro is systemd-based, but by default, neither Flatpak nor Snap are installed, and there's no software store. The Xfce installation is based on traditional X.org (version 21.1.3), with no trace of Wayland to be seen.
Front page news. There you have it, ladies and gentlemen, you don't need systemd or Wayland. Your world will not crumble.
-> After you install, you will have to make your way up the learning curve of Arch's command-line tools.
This is really my biggest bugbear about all the different package managers (and to some extent configuration managers where they exist). You have pulled your hair out thanks to the obscurities of dpkg and apt. You give an RPM distro a try, and have to learn a whole bunch of new commands to do the same thing you thought you already knew. Now it's over to pacman. If there really cannot be one package manager, why can there not be the equivalent of LSB (perhaps a bad example, as LSB is no more) or POSIX for Linux package managers. There is no reason why they can not all take $pkgmanager -install $package-name, to install, and -uninstall to uninstall it, and they can do whatever they want behind the scenes. Instead there is "install" "--install" "-i" "-S", and more. Here choice is not a good thing, it is a waste of time. Unless you are aiming to receive a certification in Linux package managers.
