I’m creating a snap utility which need to write data to files in sysfs, for example,
I’ve added and connected plug
hardware-observe in my
snapcraft.yaml (the auto-connect interface was approved on Auto-connection request: quectel-firmware-switch). But when running the snap, the daemon program in it always fails with
'Permission denied' in
journalctl log. However, the snap works in
classic mode from local installation.
Do I have to use
classic confinement for my utility in this case? Thanks for your help in advance.
