================

|
|
|
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 +chimaera+/+beowulf+ distribution and reboot
|
|
|
|
|
|
|
|
|
|
.Quick How To
|
|
|
|
|
Copy the script to +/root+, and then run as +root+ in one of four
|
|
|
|
|
ways:
|
|
|
|
|
|
|
|
|
|
1. # ./script.sh 1
|
|
|
|
|
2. # DIST=chimaera ./script.sh 1
|
|
|
|
|
3. # DE=desktop ./script.sh 1
|
|
|
|
|
4. # DIST=chimaera DE=desktop ./script.sh 1

.Description
|
|
|
|
|
|
|
|
|
|
The script performs the 2-stage migration with minimal operator
|
|
|
|
|
intervention.
|
|
|
|
|
|
|
|
|
|
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+.
|
|
|
|
|
|
|
|
|
|
Important: this script only handles systems with Ethernet cable
|
|
|
|
|
networking.
