Ah yes, that probably wasn’t working because of the issue you answered in Lxd-agent: No such file or directory - #4 by stgraber
ESC works but the time window is very very narrow unless your distribution has a build of EDK2 with an increased timeout (as we do in the LXD snap).
Right. I don’t think they have a patch for that. Are you able to point me to the commit/patch that increases it?
