No, I stay away from btrfs. I use ext4, xfs, and some reiserfs. I've written a number of times about the idiocy of ext4, a B-Tree allocator that has mkfs-time provisioning of a hard boundary between space reserved for files and space reserved for inodes. It's sheer idiocy! This dates back to the very early UNIX, what we later called the V7FS.
It really is inexcusable, since before ext4 came into being we already had not only ReiserFS but also XFS as examples of how to get around the pre-provisioning constraint, to make ALL allocations, data and inodes, dynamically, from the B-Tree.
Then we have BtrFS, which is also a B-Tree file system and also allocates space and inodes dynamically from the B-tree rather than preallocating.
Now it all goes to rat-shit.
openSuse 15 will no longer support ReiserFS. This isn't a passive move, as in "no continued support, no further fixes", but is an active move. If you have any ReiserFS partitions then they will be forcibly converted to another file system whether you want that to happen or not.
This seems very draconian to me.
Yes, I realise that Oracle are going full steam ahead with BtrFS as their anointed FS for their Linux. But what about other distributions?

While BtrFS _could_ have been a replacement for ReiserFS and a 'nicer' version of XFS, the developers went overboard and decided to do a "One File System to rule all storage" approach. Integrate all of what LVM does but without actually partitioning. Have a many other features that annoy people who don't understand it and are only relevant for server class machines and irrelevant to embedded systems or many workstations.
Resiser4 is available for kernel 4.13, which is the latest I have from repository kernel_stable. https://www.phoronix.com/scan.php?page=news_item&px=Reiser4-Linux-4.13 Why can't openSuse work that in, after all, there is a developer/group working on it. Could there be one for openSuse?
I'm not sure what you are suggesting as a universal file system. You are of course aware that Reiser is in prison, probably for the rest of his life, and not supporting the FS he devised, and I haven't heard that anyone else is, unless you are. From your post, I do not see a recommendation for a "file system that fits all." (It would be nice if it worked not only for Linux but for FreeBSD. so that exchanging files between systems would be easy, and hardware --hard drives-- would work together.) --dm -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
