Error statting /zram0: No such file or directory at boot #11

After enabling the service and rebooting (using the default configuration), I get bunch of Error statting /zram0: No such file or directory coming from udiskd at random intervals for about a minute after booting:

I still seem to get a functioning zram swap: 

               total        used        free      shared  buff/cache   available
Mem:            15Gi       2,7Gi       8,3Gi       194Mi       4,6Gi        11Gi
Swap:          8,0Gi          0B       8,0Gi

Since the message is coming from udisks2, should an issue be opened there or is there something zramd might do incorrectly?

Thank you for the report, the issue was happening because swapon was being executed inside a systemd sandbox which prevented the udev from getting the real path of the zram device
