Setting options for LUKS devices on Fedora Atomic Desktops

[siosm (Timothée Ravier)]

Article Summary:

Setting options for the main LUKS device on a Fedora Atomic Desktop system, where the root partition is located, is slightly different from a package mode Fedora installation.

Article Description:

This will explain how to manually configure the following fixes for existing systems:

• Poor performance with dm-crypt on SSD (was Application not responding under heavy load) · Issue #388 · fedora-silverblue/issue-tracker · GitHub
• Enable fstrim on LUKS encrypted partitions · Issue #31 · fedora-silverblue/issue-tracker · GitHub
• Upgrade LUKS key derivation function on (major?) updates · Issue #455 · fedora-silverblue/issue-tracker · GitHub

We may be able to fix the first two issues in an upcoming Fedora release for new installations but existing systems won’t be updated and will need manual intervention.

@siosm I’ve opened Pagure ticket #367 to track this article.

Add a preview link to that ticket when you have it ready for review in the Fedora Magazine WordPress instance.

Thank you.
