題目: Re: [DNG] automount, mount, and USB sticks
Eventually, and I kinda realized this, work may be needed to write a udisks replacement for vdev that can work off vdev without loosing functionality to udisks using applications and file managers, especially for non-Linux systems.

Nothing fancy, but as long as it works and allows for some level of control for admins, I don't have a problem with it.

Thoughts?

Yes, that would have been easier.

For whatever reason, there was a time when it kept picking new letters
if I umounted the stick, took it ouot, and put another in. Maybe there
was a bug somewhere then? But I could not rely on it always being
/dev/sdb.

Truth is, I no longer trust it to be consistent.
