No, you are wrong. There were options added to ext4 which made it
incompatible with older kernels. And a few years ago they made
this options default. Debian wheezy kernel (3.2) would not mount
ext4 created in debian stretch.
Hi!

Yep. Exactly my thought when i spent 3-hours with a server refusing to
boot after migration to a new hdd (i used a stretch flash to copy).
Who the fuck toughs it was a good idea?!! Why not call it ext5 or
ext4a or whatever?!!
