Consider a machine with a single hard drive with vast unused
space on it.
I wish to create two classes of partitions:
One class would require root privileges &/or appropriate
fstab entry to mount.
[i.e. current default behavior]
A new "thingy" [explicitly avoiding calling it a partition ;]
This "thingy" would have metadata within itself identifying who:
1. may *NOT* mount it at all.
2. mount it *READ ONLY*
3. may mount it read/write with access determined by
individual file permissions.
I'm beginning to suspect a variation of LVM might be relevant.
Haven't found appropriate docs yet.
I'm doing some experiments with USB flash drives that show
potential for illustrating effects I desire. They are *EXPLICITLY
UNSUITABLE* for my application as they are removable devices!
Any clearer than my first try?
