How many filesystems has the Linux world created in the last 20 years? Of those how many are rotting piles of tire fire?
Filesystems are hard to get right.
ZFS is the way forward. For cross compatability, for reliability, for stability, for lots of use cases.
Btrfs is another tire to throw on the burning pile of other filesystems that won't work out in Linux.
Let the down votes begin.
But Linux has some major architectural issues that eventually the Linux faithful will have to admit to.
Containers.
Filesystems.
Observability. Though bless him Brendan Gregg is trying his hardest to help here.
Portability.
And this is what is so painful for the rest of us to watch or deal with. This inability for the Linux folks to admit these glaring architectural problems. Problems they refuse to look outside their bubble to see how others solved these problems and adopt solutions that have already solved these problems. They just want to continue to bury their heads in NIH soil. And double down on trying to solve these issues, poorly, on their own without any awareness of how others have solved these issues. People outside Linux land just might have the right ideas on how to solve these problems!
But I expect no one in that camp to acknowledge this and down vote away.
Sigh.
