[Manjaro upgrade] Demo manjaro-chroot - Repair libidn2 error at boot (broken system)

Date: Jan 23, 2019 If you got "error while loading shared libraries: libidn2.so.0: cannot open shared object file: No such file or directory" at boot, it is most likely because you have not downgraded systemd packages to 239.6-4 (version currently available in Manjaro repositories) and kept version 239.3XX-X instead. This is a demo of manjaro-chroot, which allows you to do a chroot for a Manjaro system with one simple command. It works great for simple case, but for more fancy configuration or specific hardware, using a manual chroot may be needed. In that particular case, you may repair your system simply by enabling downgrades (pacman -Syyuu, pamac upgrade --enable-downgrade, or equivalent).
