Encryption without LVM on Devuan

2018-11-24
, , , ,

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.

  • Where a / (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.

TODO - tested and working, though my most recent Lubuntu experimentation has problems I'm still troubleshooting.

At best, my computer hangs when prompting for a password. I think this is related to the 4.4.14 kernel but have not confirmed this.

These instructions are a lot easier than they seem, and a smart and patient beginner will be able to follow them!

  • These notes were made from instructions from Slackware "current", as of 2016-11-05, and have been tested on Slackware 14.2, and 14.2 32bit.

  • These notes were made on an everyday system with one hard drive which I completely formatted for this purpose.

    • If you are a new user, it is strongly recommended that you remove all hard drive's your using and do this on a spare unused/empty drive.

  • This concept and these notes build a full-disk Slackware installation which also uses LVM. You can safely ignore the entire LVM post and just follow this one.

A malware scanner.

Mostly-meh.

  • Their portable scanner is still just an installer.

  • It found an Wajam plugin from Magic Camera, presumably installed for either Internet Explorer or Edge.

    • During scanning, it claims to have found infected files, but those files were neither reported at the end of its scan nor found in its quarantine. What gives?
