It's OT but how many people actually use RHEL? Or CentOS (more likely). I'm not a fan of systemd, but have really loathed CentOS/RHEL compared to Debian/* for years.

I was working at a place a few years ago where I had to move a whole bunch of applications, running on Ubuntu Hardy circa 2008, to new servers (well VMs), as the servers were being decommissioned. A lot of the applications were running on Ruby 1.8 which newer versions of Ubuntu don't provide packages for, and it's not very easy to compile it yourself due to dependencies on old versions of OpenSSL. We upgraded some applications to newer versions of Ruby, however some weren't worth the effort or risk (before Ruby 2, even a patch level change likely had breaking changes).

Although other systems were running Ubuntu, we decided to go with CentOS 6 for these systems - mainly because it was preferred by the current era of sysadmins. It also had packages for Ruby 1.8 or at least the correct dependencies (I can't remember exactly). And even better, although it was released in 2011, it is still supported until 2020.

If I was going to do the same today I'd just use Docker, but it was fairly new back then.

Worse, I browse without javascript and their page has no text. It's utterly terribly designed to be an open source information page.

Even as paying customer I wouldn't want to put up with that shit.

Re: Mozilla, they are aware, and there are a couple of about:config flags to enable text reflow on page load and on tap-to-zoom, but they're disabled by default "due to a number of reasons (mainly performance)".

Slightly off topic. I chose btrfs as my main filesystem recently on a system running Ubuntu/Xubuntu. I have done some research on backing up (with the advantage of snapshots) but it looks like there aren't (m)any graphical tools (this gets a little more confusing with /@ and /@home subvolumes on the same partition being treated separately for snapshots, AFAIK).

Do you manage it all from the command line and/or do you have any suggestions for graphical tools to do "as-is clones of entire partitions" (and also incremental backups) to local external drives (not over the network)? Or if you could point to any great documentation or blog posts on this topic, that'd be helpful too (I have read some bits of the btrfs wiki and the btrfs parts in the Arch wiki).

Currently I'm doing a plain rsync using Grsync, and not really taking advantage of btrfs features like snapshots.

The main reason I'm looking at avoiding the command line is to make it easier for others around me to use it.

Unsurprising. Red Hat has not hired upstream Btrfs developers for years, where SUSE has hired bunches. Meanwhile Red Hat has upstream ext4, XFS and LVM developers.

If you're going to support a code base for ~10 years, you're going to need upstream people to support it. And realistically Red Hat's comfortable putting their eggs all in the device-mapper, LVM, and XFS basket.

But, there's more: https://github.com/stratis-storage/stratisd

Btrfs has no licensing issues, but after many years of work it still has significant technical issues that may never be resolved. page 4

Stratis version 3.0 Rough ZFS feature parity. New DM features needed. Page 22 https://stratis-storage.github.io/StratisSoftwareDesign.pdf

Both of those are unqualified statements, so fair or unfair my inclination is to take the project with a grain of salt.

Happy to see his Patreon is looking "healthier". I mean $1500/m isn't really that much but I'm sure last I looked it was much lower. In other news.. consider supporting the people that support you! Personally, I spent over $100/month on Patreon. Most of those are creators rather than open source people but there are a couple of open source ones such as Ondřej Surý who works on PHP packaging in Debian/Ubuntu

Joey Hess, a formerly prominent Debian developer and author of git-annex, etckeeper and a bunch of other open source projects is also on Patreon: https://www.patreon.com/joeyh

Unfortunately, he's only getting $500/m, which isn't much even for someone with a very "off-grid" life: https://joeyh.name/blog/entry/notes_for_a_caretaker/

my line for snapshots

btrfs subvolume snapshot /source/drive/folder/ /source/drive/folder/.snapshots/snapshot-`date +"%Y-%m-%d-at-%I-%M%P"`

this will create a snapshot with date and time attached to the snapshot name

you can more info here

https://btrfs.wiki.kernel.org/index.php/SysadminGuide#Managi...

make sure to remember to delete old snapshots, otherwise you'll run out of disk space and not know where it went

EPEL gets security updates just like fedora does. Packages are usually maintained in the same gut repositories. However there is no guarantee that you will receive security updates as there is no support contract. But you have a similar problem in Debian if the maintainer isn't keeping up

Debian doesn't have this problem: the security team is collectively responsible for making security updates and frequently creates updated packages without maintainer involvement. I'm not familiar with the Fedora process, but they seem to have a security team and a system of security advisories, which EPEL does not appear to have. Doesn't sound like the same at all. Sure, most of the time packages in EPEL (and in Ubu…

EPEL is part of the Fedora project and shares the packaging infrastructure.

Well I used btrfs as a root filesystem for quite a while, until I realized it was pig slow for sync() -- I mean, it would take AGES to do and apt-get upgrade for example. I ended up having to do some tasks using 'eatmydata' [0] to make it all better, risking filesystem corruption in trade for speed. Also, at the time, there was no functioning fsck.

So I moved back safely to ext4 and never looked back!
