Ikey Doherty’s Serpent OS Changes Name to AerynOS
Why the big change after all this time developing this new Linux distro? Well, Ikey Doherty says that “the “Serpent OS” name was a quickly chosen name that stuck.” In addition, the developer thinks that “serpents” are often associated with negative connotations and that “Serpent OS” is not the most inviting name for a project.

Edmundson: a modern Plasma Login Manager
KDE contributor David Edmundson has published a blog post about improving KDE Plasma's login experience by replacing SDDM with a new Plasma Login Manager.
It's worth stressing nothing is official or set in stone yet, whilst it has come up in previous Plasma online meetings and in the 2023 Akademy. I'm posting this whilst starting a more official discussion on the plasma-devel mailing list.
Oliver Beard and I have made a new mutli-process greeter, that uses the same startup mechanism as the desktop session. It doesn't have all the features that we propose at the start of the blog, but an architecture where features and services can be slowly and safely added.
That discussion is here for those who would like to follow along. The prototype is currently in two repositories: plasma-login for the frontend work, and plasma-login-manager, which is a fork of SDDM.

How to Get Root Access Inside Vim If You Forgot to Run It with Sudo
Vim is a highly configurable and powerful text editor widely used in the Linux and Unix world. It is favored by system administrators and developers due to its efficiency, keyboard-driven workflow, and extensive feature set.
Unlike other editors, Vim operates in multiple modes:
- Normal mode: For navigation and commands.
- Insert mode: For editing text.
- Command mode: For executing commands like saving and quitting.
One common use case for Vim is editing system configuration files. However, these files often require root permissions, and forgetting to open them with sudo can be frustrating when trying to save changes. Fortunately, there’s a simple solution.

How to Change a User’s Login Shell, Uid, or Home Directory With Usermod
Managing user accounts in Linux is a crucial task for system administrators, and the usermod command provides an efficient way to modify user information. This command allows you to change a user’s default shell, unique user ID (UID), home directory, and group memberships.
In this article, we will walk through how to use usermod step by step to make these modifications safely and efficiently. We will cover useful commands, practical examples, and best practices to avoid permission or access issues.

Bypassing Ubuntu's user-namespace restrictions
Ubuntu 23.10 and 24.04 LTS introduced a feature using AppArmor to restrict access to user namespaces. Qualys has reported three ways to bypass AppArmor's restrictions and enable local users to gain full administrative capabilities within a user namespace. Ubuntu has followed up with a post that explains the namespace-restriction feature in detail, and says these bypasses do not constitute security vulnerabilities.
While a superficial observation of the application of user namespaces may indicate privileged (root level) access, this is a fictitious state that is operating as expected, with access control still mapped to the real (root namespace) user's permissions. As such, these bypasses do not enable more access than what the default Linux kernel unprivileged user namespace feature allows in most Linux distributions. They do, however, demonstrate limitations that we are looking to address in order to strengthen existing protections against as-of-yet-unknown Linux kernel vulnerabilities.LWN covered Ubuntu 24.04 LTS last May.
