>Description:

Like on other install media, when the install is done and sysinst
returns to the main menu, on the USB stick installer sysinst tells you
that you can remove the boot media.

Unfortunately, it's lying. If you remove the USB stick at that point,
it's still mounted, so afterwards it needs to be fscked, and, worse,
the system then wedges itself when you try to reboot.

This is true for the USB stick install images that have the complete
install sets on them. As of this writing, we are still missing
installer-only USB stick images.

>How-To-Repeat:

as above.

>Fix:

Dunno. Maybe make it handle the install media like the other
installers (although that might be a bit drastic) ... that or arrange
to make that message different for the USB installer, something
explicit like "do not remove the boot media until you have shut down
the system", since I'm sure a lot of people know how it normally works
and won't notice the mere absence of a routine message.
