Boot fails when config.boot content is based on output of: show config commands
Open, LowPublic
Actions

Description

To me the "show config commands" format is easier to read and compare between configfiles.

However it seems that VyOS doesnt like if the /config/config.boot is in the "commands" format.

Plenty of errors during boot that ends with "Configuration error".

I can however restore the json-format from a backup since it works to login using some of the vyos-accounts that existed before the above attempt of "cp config.cmd config.boot". After restore I just reboot with "sudo reboot now" and the box is back to how it was before my attempt.

So a bug/feature request would be if either the config.boot format can be changed to the commands format or at least that vyos-configd (or whoever is reading the config.boot during boot) can be made compatible with the commands format?

Another option/workaround would be if something like "config replace" would be supported where the input could be a "config.cmd".

I found this as a workaround but again would be handy if things would work out of the box :-)

https://forum.vyos.io/t/convert-vyos-set-commands-in-to-vyos-config-offline/11268/5

The workaround is basically:

  1. Copy /config/config.boot to /config/config.empty
  2. Edit /config/config.empty so only the section of interfaces remains and the magicstring at the bottom (so migration wont trigger when it shouldnt).
  3. Enter config-mode with "conf".
  4. Type and press enter: load /config/config.empty
  5. Now over current SSH-session simply paste in the full list of set-commands.
  6. "commit", "save" then "exit" and finally "reboot now".

Now you have transfered a config based on set-commands onto a (new) VyOS box.
