I think I eventually tracked the problem down to installing sys-fs/cryptsetup ages ago and subsequently doing nothing with it, hence out of sight, out of mind. It brought in lvm2, which once again I don't use, but out of sight, out of mind, which brought in thin-provisioning-tools. Just at the moment with my 3 versions of Ruby and KDE doing a large upgrade, I was swamped with "info" so it took a bit to find my way around this stuff and find the appropriate flags to set/unset. Thanks to those who provided thoughts, Andrew
