Gentoo already contains many packages, but not all. Installing packages that are not (yet/anymore) part of the official Gentoo repositories can of course be done outside of the Gentoo package manager portage, but that might mess up things. Luckily, Gentoo allows for local repositories that can work in the same manner as the standard Gentoo repos.
Storage replication using DRDB on OCI
In a previous blogpost a setup of Distributed Replicated Block Device (DRDB) using local computers was described. This blog post is about DRBD on Oracle Cloud Infrastructure OCI.
Gentoo on OCI - part 1
Most of this blog has actually been about on-prem stuff, but hey, it is 2024 so let's do something in the cloud. Let's try to put Gentoo Linux on OCI.
Storage replication using DRDB
Storage on a personal computer, or laptop, is always tied to the physical machine. It would be nice to have it synchronised between all of my computers. Linux has this possibility with a Distributed Replicated Block Device (DRDB).
Complete linux system encryption
A quick guide on how to encrypt a complete Gentoo Linux system. By now I have encrypted all my laptops and my little home server. This blog is just a reminder on how to do it, from A to Z. Perhaps it is beneficial for others too.
Regenerate Dovecot certificate
After upgrading my Gentoo based home server, the e-mail client on my laptop could no longer make a connection to the IMAP server. It seems that Dovecot v2.3.20 requires stronger encryption.
Encrypt an existing root disk
Sometimes I get struck by a sense of security consiousness. This time I realized I have all my content on simple btrfs formatted disks, without any encryption. That's not very secure, is it?
Backups
Of course I hope I never need a backup, but just in case...
Making a btrfs RAID-0 disk group
Alpine Linux persistent storage on the Raspberry Pi
Alpine runs in memory on the Pi, which is great for performance, security, and for minimizing wear on the SD-card. The downside is that it has no persistent storage. Everything done on such a system is cleared out on reboot.
