On shutdown or reboot process I’ve noticed a failed process as on topic title.
How could I fix this issue ?
What’s the actual problem? This sounds like a 100% harmless error if it’s only happening during a reboot.
I 'm not able to understand what it mean so I’ve asked here. Im not so sure it is an harmless error
Might be harmless and “by design” (since its the persistent directory so it should be unmounted among the last mounts when shutdown/reboot) but it doesnt look good.
Best would be if @gianry creates an entry about this at https://vyos.dev and include the bootlog (journalctl -b and/or sudo dmesg) so this can either be fixed or documented as “expected because reason x”.
