@jk the reason there are different distros is they meet different needs.
RHEL: corporate linux
Fedora: unpaid dev for rhel
Arch: true rolling, minimal package changes from upstream
#Slackware you are expert, want vanilla upstream, patrick v. BDFL
#Debian install once run forever. Really. Sid/testing semi-rolling
Ubuntu: swahili for "can't install debian"
TinyCore: 26 MiB full OS install to RAM. Really.
#Alpine very groovy tech
Mint: new user choice 1
SLED/SUSE: Not rh
And so on.
