Adjusted patch file changed tab to 4 spaces and fixed typo.
 (orig file didn't use tabs)

I've attached a patch file.

AIUI it is better to specifically path /bin/bash rather than via env,
escpecially when we know for sure where bash is located

 - save [with verbose] orig sources.list (mv -v)
 - save file permissions and timestamps [with verbose] with cp (cp -vp)
 - adjust sed to use more normal "sed -i" form...?
 - indent cat EOF (better readability).

Also fix http:// ref to https:// with a server that is valid.



Not tested not sure if /etc/network/interfaces change is universal
or not.

Perhaps change line 7 for which vim instead of vim.tiny?

Also, if the keyring package (.deb file) is "stable", why not verify
it's checksum?

Passes shellcheck cleanly.

Cheers
A.

Yes, I have been working on this.

Attached is the script I have been testing. It single steps through.

I don't propose we publish the script but it makes testing quicker. Or 
just run the commands manually. It requires 2 passes.

This is stolen from the forums and modified slightly. Most of the wording is
taken directly from the post, but I've added details so I can find everything
in one spot. Taken from https://dev1galaxy.org/viewtopic.php?id=3044

install eudev and let it fail. This might save some time on the first reboot.

reboot and install eudev, remove or purge systemd if it doesn't get
removed automatically. (possibly libnss-systemd also)

(optional) install libelogind0 if you want to replace libsystemd0.
  Without elogind, it's not pulling in the desktop apps.

Beware of "predictable interface naming" - depending on how you configure your
network, you might see your NIC names change.

Re: [DNG] buster to beowulf

[Bernard Rosset via Dng]

Quite an old thread without any reaction to it, but I myself attempted a 
migration from buster to beowulf today, and thought about sharing my 
experience.



What is the current recommended way to crossgrade from buster to
beowulf (so I can test it properly)


I followed 
https://devuan.org/os/documentation/dev1fanboy/migrate-to-ascii which 
happened to roughly do the trick.


To grab the Devuan keyring, temporarily use ascii repository.


And what logging would be useful to do while I do this?


I suppose you could record your session the way Debian recommends it: 
https://www.debian.org/releases/stable/amd64/release-notes/ch-upgrading.html#record-session



In particular, is there any useful way to get a log during reboot to
the new system?


On top of the session recording from above, I guess digging into 
/var/log/dmesg, /var/log/messages (which might include the former) and 
any other resource deemed useful.
I got myself some errors on boot I was not able to find in the logs 
(probably happened before filesystem was mounted)


I am now having to deal with ugly network interfaces name, and a couple 
related quirks & bruises everywhere.
My case was particular, as having installed buster w/o network from the 
full DVD (not netinst), I ended without a desktop GUI & a minimal 
install... I don't know what went wrong with that official Debian installer.
I had to use buster, as the kernel used in stretch (and ascii) was too 
old for my network hardware which ascii did not detect.


I happened to notice, for instance, that USB drives were not popping up 
on plug in Xfce4 GUI... Might be an install quirk... or a software defect?


Overall, it seems to be working. The basics are there.
