I created a personal firstboot script (for templating VM) but I have an error in the /etc/rc script : line 138, 144, 147: [: =: unexpected operator It's a problem with ${root_rw_mount#[Yy][Ee][Ss]} = "" I think you must write : "${root_rw_mount#[Yy][Ee][Ss]}" = "" (add "" around the var)
^Triage: assign. To submitter: is this aging PR still relevant?
Hopefully this is no longer an issue since we use checkyesno now.
