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
