Out of space on boot zpool and cant run updates anymore
So i think i fixed it...
I ran zfs list -t snapshot | grep bpool to list of all the snapshots for the boot pool. Then sudo zfs destroy bpool/... for a handful of snapshots starting from the top of the list until zpool list showed bpool at around 60% CAP. Then ran sudo apt upgrade and it ran mkinitramfs successfully! And now my bpool is around 70% :shrug:
