TLDR: Ubuntu Pro offers additional security patches to packages found in the universe repo. Universe is community maintained so Ubuntu is essentially stepping in to provide critical CVE patches to some popular software in this repo that the community has not addressed.

I suppose it depends on how you look at it but I don’t really see this as withholding patches. Software in this repo would otherwise be missing these patches and it’s a ton of work for Ubuntu to provide these patches themselves.

Now is they move glibc to universe and tell me to subscribe to get updates I’ll feel differently.

I’ve had two Dell laptops that ran Ubuntu perfectly. Dell sells laptops with Ubuntu pre-installed and also certifies models for Linux. Their Linux support is top notch in my experience.

Honestly this is probably me going off of outdated or even incorrect information. The fact that it has little adoption for that use case or as a root filesystem is probably the larger factor.

It’s been awesome to see Ubuntu embrace it over the last few releases though and that’s certainly starting to change things but since it’s not part of the Linux kernel that gives most other distros pause I think.

I don’t believe it’s been marked stable yet but it doesn’t suffer from the raid write hole like BTRFS and claims to be more performant than ZFS’s implementation.

With it being merged into the kernel it should get much wider use and hopefully that helps it reach stability.

I was referring to its lack of use as a root filesystem. It’s primarily used for large storage arrays both at home and in data centers.

I’m really excited for this. If it lives up to the hype I think it could become the defacto filesystem some day.

BTRFS, despite being a great filesystem, got a bad rep mostly due to its poor RAID5/6 implementation. It also lags behind in performance in many configurations and has been mostly relagated to a specialty filesystem. While it could make a great root filesystem few distros have adopted it as such.

ZFS has been similarly pigeon holed. It’s typically only used for building large arrays because it’s not very safe when used on a single device (edit: After some research this may not be true and is probably outdated or incorrect info stuck in my head) . It also lacks a lot of the flexibility of BTRFS, though you could say it trades flexibility for reliability.

bcachesfs on the other hand feels like it has the potential to be adopted as a root file system while also providing replication, erasure coding, high performance and snapshots; something that no filesystem has managed to date, at least on a wide scale.

Okay so I just read up on this. It’s it true that TPM backed FDE only allows snaps?!?

Debs are completely unsupported?
