I thought I was old-fashioned for not using LVM and encrypting disk data, e.g. https://wiki.archlinux.org/title/Dm-crypt/Encrypting_an_entire_system#LUKS_on_LVM, but perhaps not. I keep thinking I should do it at the next install. Back to OP Pete's original perennial question of whether a partition can grow, LVM ‘fixed’ that if put in place in advance. -- Cheers, Ralph.
