# make a snapshot with snapper before: 'sudo snapper create --description 'before-uutils' --userdata important=yes -t pre'
# and after: 'sudo snapper create --description 'after-uutils' --userdata important=yes -t post --pre-number [NUMBER OF THE SNAPSHOT THAT WAS MADE BY THE PREVIOUS SNAPPER RUN, CHECK WITH 'sudo snapper list']'
# before running this, install uutils to /usr/bin  (compile and copy the generated coreutils binary to /usr/bin)
# Run this first with sudo sh, then run 'sudo rpm -e --allmatches --nodeps coreutils', and then run this with sudo sh once again.
# Only reboot AFTER running this after you remove coreutils with rpm.
# Remember to install the empty .rpm coreutils metapackage with zypper and then addlock coreutils and coreutils-single on zypper.
