Some notes:

1. The old syntax is quite terrible. It breaks if an image is named disk-install or running or any remote protocol. There needs to be a cleaner syntax for it, such as copy file from image My-Image/usr/local/foo to path /tmp/foo or show file in remote ftp://ftp.example.net/foo.
2. 'Image tools' isn't exactly a descriptive name for it. It does four operations:
   • show: List files in a directory, or spit information about a file followed by its contents (hexdump if it's binary).
   • copy: Copy a file or directory from one place to another (it can merge directories).
   • delete: Deletes a file or directory (doesn't work remotely).
   • update and updateone: Updates an image's config directory with rsync (the only part directly related to image manipulation). This is actually called clone in the CLI.
3. show, copy and delete should probably be moved to a separate (new) module related to file operations (and coupled with vyos.remote) whilst update needs to become its own thing (a helper script, perhaps).

@NikolayP Could you test if all works fine?
Check the real generated firewal rules.

Is it an actual task? If yes, can someone explain which configuration you expect from keepalived.conf or radvd.conf?
As I see PR 9aad6f was merged.

It requires option -6
For example:

sudo ip -6 rule add prio 10 from de:de::1 lookup 5

Show v6 rules:

vyos@r11-roll# sudo ip -6 rule show
0:	from all lookup local
10:	from de:de::1 lookup 5
32766:	from all lookup main

The situation has not changed in VyOS 1.4-rolling-202201070726

Tested in VyOS 1.4-rolling-202201060842
Works

@rps this did not make it into 1.3.0, but was discussed recently and will be addressed; it is, as you point out, a regrettable omission in functionality

Do we know if this made it into the 1.3.0 release or is this now a 1.4 issue?

Updates the vyatta-conntrack package to work without legacy firewall and fixes the op-mode commands. Should also fix some conntrack functionality (untested).

Fixed for 1.4 in T4128 with update "keepalived".
In 1.3 we don't update this pkg and it still has this bug.

relaxes the condition to escape non-ascii bytes. Updating the commit id in the Dockerfile and relaxing the ascii restriction in configsource.py will allow unicode chars in config.
