It used to (it works in Core22) but seems systemd dropped support for it, though I can’t actually find with which version but it looks like the documentation referring to it:
To configure this feature, is it correct to change the cmdline.txt-core in the gadget snap source which end up in /run/mnt/ubuntu-seed/cmdline.txt on the imaged system?
There are other instances of cmdline.txt on the imaged system , not all identical.
Also should changing it and rebooting be enough or does the gadget snap need to rebuilt and the device re-imaged?
