The size of the com.apple.os-update-xxx volume on my iMac running Monterey has increased. Is this a problem?

iMac 27″ 5K, macOS 12.2

EDITED - the APFS Snapshot ⁨com.apple.os.update-...⁩ 15.2 GB    disk3s1s1 is the Sealed and Read Volume in which the Operating System resides in.


It can not be opened except by Apple and usually only when there are updates to Monterey so yes - it would appear Normal.
