free-form notes

Would be nice to have some kind of wizard-like user space tool that would allow virtualized data management on Linux.

Need to scope the requirements.

Do we want some kind of permanent storage management (disk/CF/optical)? Device maintenance? Ways to drive SMART, or other testing?

Do we want some kind of storage pool management (manage LVs, manage pools [for fs's that understand them])?

Do we want some kind of file system managment (create, check, remove, expand)? Managing /etc/fstab, /etc/exports, and the automounters? boabab (disk usage analyzer)

Do we want some kind of data management (replicate/migrate/backup/mirror)?

So I think we can start small. Take a common TUI utility or two (fdisk or mdadm) and try constructing a GUI around it.
