The matter is that BTRFS had many early adopters just because it is -
and has been for long now - in the mainline Linux kernel, so supposed
stable and good choice for the future.

To be honest (and not wanting to troll, promised) this is the only
single reason for which I use BTRFS on 5 of my 6 machines at home - just
because I thought that "Just upgrade the distro every 6 months and it
will become better and better over time, no hassle, make my life easy".

OTOH my 6th machine runs native ZFS on Linux, and I have to tell that it
shows orders of magnitude better performance and never gave me a single
problem in several (3 ?) years. Only upgrading the distro is always a
big frightening and problematic. And initial installation was a bit tricky.

Probably a lot of BTRS early adopters choosed it for the same reason why
I did : Included in the standard kernel, easy to install, and *expected*
to improve quickly - yes, I already made the move back and forth twice,
between ext4 and BTRFS, on 2 machines... About one year ago I choosed to
jump "for good" and stay, but performance degrades so quickly and so
much that every couple of days I wonder if I won't rollback to ex4 again
(and again), or shift to ZFS once for all and just forget about it...

Everytime I show my Linux machines to friends and say : “Hey, I got the
most advanced filesystem on earth !” I soon get the answer “Oh boy,
that's the slowest machine boot and FS I've ever seen since I was
reading floppy disks on my 386SX in 1991 ! Can you really live with this ?”

So, for "not quite there" and the return codes "+20" that have been a
minor pain in the arse for a couple years but the line is still in the
code... I can understand developer's PoV, been there, done that, but
still, BTRFS might in the end lose a numer of its early adopters if it
keeps being "not quite there" too long.

Shitfing to ZFS is just a PPA and 2 apt-get install commands away... It
will definitely be easier than start playing with mainline PPA Ubuntu
kernels...

Kind regards.
