A filesystem I use because of checksumming and de-duplication.
Very good, although I've had a sketchy history with it. I've used multiple versions of it, sometimes mounting the same partition with different versions of it.
I stopped using it because I lost trust in its reliability.
This page is about ZFS-fuse, the ZFS attempt for Linux
ZFS is a filesystem.
I have abandoned this filesystem because it is about as closed as it can get without being officially closed. It's hampered by awkward licensing and patents making it intentionally incompatible with the GPL.
Even if it was made to work perfectly, running under FUSE is sub-optimal.
It also seems horrifyingly complex to use. Seriously.
Its checksumming is important for The Chain of Trust.
An interface for userspace programs to export a filesystem to the Linux kernel.
Running things under FUSE is sub-optimal. It's better to run under the kernel directly. However, userland stuff is the only way to achieve certain effects, like everyday user control or to work around licensing issues.
acronym: Filesystem in Userspace
A disk/volume management thing, with SoftRAID and more.
Required kernel patching and I never really did figure it out.
- Enterprise Volume Management System
LVM won out.
