This is a script for migrating from a Debian +buster+ system to either
Devuan +beowulf+ or Devuan +chimaera+.
This is a script for migrating from a Debian +bullseye+/+buster+
system to Devuan +chimaera+/+beowulf+.
It has two stages:
1. replace the init system to be +sysvinit+ and reboot
2. upgrade to the standard +beowulf+/+chimaera+ distribution and reboot
2. upgrade to the standard +chimaera+/+beowulf+ distribution and reboot
.Quick How To
Copy the script to +/root+, and then run as +root+ in one of four
ways:

The script performs the 2-stage migration without operator
intervention, with a first stage ending in reboot after having primed
the boot to enter the second stage automatically. It then performs the
second stage, still without operator intervention, and ends with a
subsequent reboot. Note that the second stage also includes an
explicit +sshd+ as a possible "resuce entry" option if it runs into
trouble.
.Description
The script will migrate the system to +beowulf+ unless +DIST=chimaera+
is set in which case it will migrate to +chimaera+.
The script performs the 2-stage migration with minimal operator
intervention.
The script may uninstall the desktop environment used in +buster+ and
1. The first stage prepares the system for using +sysvinit+ rather
than +systemd+, and this stage ends in requesting a manual reboot with
the system primed (via +/etc/rc.local+) to enter the second stage
automatically at next boot.
2. The second stage performs all requested installations for the
target +chimaera+/+beowulf+ system and the stage ends with another
request of manual reboot. The second stage also includes an explicit
+sshd+ as a possible "resuce entry" option if it runs into trouble.
The script will migrate the system to +chimaera+ unless +DIST=beowulf+
is used in which case it will migrate to +beowulf+.
The script may uninstall the desktop environment used in Debian and
then not install a desktop environment unless +DE=desktop+ is set in
which case it will install +xfce4+ (using +task-xfce-desktop+). The
script also handles +xfce+, +mate+, +cinnamon, or +kde+ instead of
+desktop+.
Note that this script only handles systems with Ethernet cable
