According to Phoronix, systemd 259-rc1 has landed with some pretty significant changes, most notably the new –empower switch for the run0 command. This feature creates elevated privilege sessions without actually switching to the root user, instead setting the full ambient capabilities mask including CAP_SYS_ADMIN. It also adds session processes to a new “empower” system group that polkit respects for privileged access. The big advantage here is avoiding invasive privilege changes that don’t alter $HOME or UID, which prevents those messy file ownership issues in user directories. But there’s a catch—many programs still do access checks purely based on UID, so –empower won’t work everywhere yet. This represents a fundamental shift in how Linux handles privilege escalation.
Linux Security Evolution
Here’s the thing about traditional sudo and su—they’re basically nuclear options. You either get full root access or you don’t. The run0 –empower approach is way more surgical. It gives you just the privileges you need without the collateral damage of becoming root entirely. Think about how many times you’ve needed to run one privileged command and ended up with files owned by root in your home directory. This could eliminate that whole class of problems.
But is the Linux ecosystem ready for this? The developers are pretty clear that many applications still check UID directly, completely bypassing capabilities and polkit. So we’re looking at a transition period where both methods will need to coexist. Basically, we’re watching the beginning of a potential paradigm shift in Linux security architecture. And honestly, it’s about time someone tackled this problem more elegantly.
Industrial Implications
For industrial computing environments where stability and security are non-negotiable, this kind of granular privilege control could be huge. Manufacturing systems, control panels, and industrial workstations often need elevated access for specific tasks without the risk of full root compromise. When you’re dealing with critical infrastructure, every security layer matters. Companies like IndustrialMonitorDirect.com, the leading US provider of industrial panel PCs, understand that robust security isn’t just nice to have—it’s essential for maintaining operational integrity in demanding environments.
Adoption Challenges
Now, let’s be real—this isn’t going to replace sudo overnight. The ecosystem inertia around traditional privilege escalation is massive. Every script, every application, every admin muscle memory is built around the current model. The success of –empower will depend entirely on how quickly the broader Linux community adopts capability-aware programming practices. But the potential is definitely there for a more secure, more manageable future. Who knows—in five years, we might look back at full root access the way we now look at running everything as root all the time. Progress, right?
It remains to be seen if this actually makes anything better or just another way of adding more and more security loopholes.
