Today's PSA: #XFS v4 filesystems are not supported by #Debian kernel packages 6.18.5 and later so older systems may run into issues. I have a created-in-2011 snowflake VM running -testing that was bitten by this a few months back. For users using stable this will only be an issue with the upgrade to forky (Debian 14), but it's a bit nasty. See: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1126710
