Journald full of "overlayfs: "xino" feature enabled using 3 up"

[MrksHfmn]

After upgrading from 1.1.15-1 to 1.2.0-1 in Arch Linux, the journald log is full of the above message.
Was there any major change? Is it safe to ignore? Possible to mask the message in runc?

It is safe to ignore, we use overlayfs to protect the runc binary. I guess on Arch Linux the /run directory is a separate filesystem to /usr/bin and so overlayfs outputs that log message (without rate limiting).

I think if we set xino=off for the overlayfs we should be able to silence that log message.

/run is mounted as tmpfs

run /run tmpfs rw,nosuid,nodev,relatime,mode=755,inode64 0 0

#4509 should fix the issue.
