i want to have full disk encryption: /home and /root. i don't care about /boot. i would like to use only 1 password to open all the partitions and i want to be able to easily install new system (not system upgrade but clean installation) that will use my /home partition
what's the best partitioning?
multiple luks partition? seems like there is a lot of manual configuration at installation time and it's not always working: https://unix.stackexchange.com/questions/392284/using-a-single-passphrase-to-unlock-multiple-encrypted-disks-at-boot
lvm on a single luks partition? can ubuntu installer reuse partition from envrypted lvm?
any other partitioning?
