Support Escalation Engineer at a tech vendor with 10,001+ employees
Daily workflows have become streamlined and security-focused for professional operations
The biggest pain point for me personally, and something I hear from colleagues regularly, is NVIDIA GPU support. It's still not where it needs to be out of the box. You have to enable RPM Fusion, install proprietary drivers manually, and if you're not comfortable in the terminal, that process can be genuinely frustrating. For a platform that gets so many things right, this feels like unnecessary friction. I understand there are licensing complications with NVIDIA, but from an end-user perspective, it's still a real barrier, especially for newcomers coming from Windows or even Ubuntu. Another area is the shorter support life cycle. Fedora Linux only supports each release for about 13 months, which means you're basically upgrading every six months if you want to stay on a supported version. For a personal workstation, that's manageable, but when standardizing across a team or a small organization, that frequent upgrade creates overhead. Finally, out-of-the-box multimedia support is lacking; things such as MP4 files and H264 codec support require additional steps because of licensing reasons. I understand why, but for someone setting up Fedora Linux for the first time, it's a confusing experience. A few more things come to my mind regarding Silverblue specifically. Although I'm excited about it, there are still some rough edges that need to be smoothed out. The biggest one is application compatibility. Not every application works perfectly in a Flatpak or container-based workflow. Some tools, particularly older or niche DevOps tools, still expect traditional file systems, and getting them running on Silverblue requires workarounds that frankly shouldn't be necessary. For Silverblue to really take off in a professional environment, that application compatibility story needs to improve significantly.

Runs efficiently across devices and streamlines penetration testing workflows
Kali Linux could be improved by including more tools. I would personally like to see improvements in Kali Linux, particularly regarding Grub issues that sometimes occur when installing the VM. Additionally, I have experienced problems when updating Kali Linux from a higher version to a lower version, which resulted in crashes. These Grub issues should be resolved. I face significant challenges with Kali Linux regarding a major issue with the Grub loader becoming corrupted, which makes it very difficult to recover data.
