I received an SSD from a friend that I’m trying to split between my Windows and Manjaro installations. My Manjaro installation is encrypted and in my search for guides on how to add the new SSD partition I’ve come across horror stories of LUKS not being amenable to the addition of partitions in various ways; generally leading to data loss.
So I have a couple questions:
is adding an ext4 partition to my system so that I only need one password on boot to decrypt all partitions possible?
If so, how do I go about it?
If not, is adding the partition to my system as an unencrypted partition safe (i.e. I don’t have much more of data loss risk than I would with normal partition editing) and would it compromise the rest of my system’s security?
