Honestly, I didn't think that SSDs operated too differently to HDDs but apparently not.
From a quick piece of research it seems like you need to overwrite at least twice to cover all pages in the SSD -> https://apple.stackexchange.com/questions/6278/how-to-securely-erase-an-ssd-drive
you need to absolutely wipe it all, rm won't be enough
cat /dev/zero > /dev/sda
(Oh also most distros require --no-preserve-root these days since people run internet code arbitrarily )
