These instructions were tested, and re-tested multiple times on devuan_ascii_2.0.0-rc_i386_dvd-1 on bare metal. They worked fine, but they magically stopped working, and so I'm giving up on this technology; it's too fucking hard to use.
- Given a hard drive which has regular partitioning and not LVM.
/(root) partition is encrypted (dm-crypt) and in use.
- Such as with an earlier release of Devuan
Install Devuan, re-using the encrypted partition without re-encrypting/formatting from scratch.
Note - I will be writing separate instructions on how to manually make and manage encrypted partitions.
For more information on encryption, see dm-crypt.
