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.
Computer security: Devuan + dm-crypt >
Devuan's installer has an encryption feature, but it formats your whole hard drive and uses LVM, neither of which I want.
- 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.
Debian, Devuan + Security >
Problem: Keep an air gapped (airwalled) computer updated via a sneakernet.
This project focuses specifically on Devuan, though it ought to apply any Linux distribution based on Debian.
See also: APT, the package management tool/system for Debian.
Problem: On Devuan-1.0.0-jessie-i386-DVD,
avconv crashes while building a video from an image and audio. It worked until a recent update.
According to old notes,
6:11.9-1~deb8u1 worked. However, I do not know if a more recent version worked before I noticed this problem.
