I'm not 100% sure, but I believe it's because snapshot information is stored
in the filesystem superblock, and that's all that can fit in the space
available in the superblock.
This is the same thing that came to my mind, but in the handbook page I found:
"Active snapshots are recorded in the superblock so they are
persistent across unmount and remount operations along with system
reboots."
1) what an "active" snapshot is?
2) is that limit limited (...) to active snapshots?
Tnx
