When you're running a server, such as ext2srv or dossrv. If I recall
correctly, this was discussed before.

No. How many characters can be stored in an absolute pathname is
program-dependent.

rio windows don't scroll by default. To enable scrolling for a certain
window, middle-click and hit scroll, or type

	echo scroll >/dev/wctl

To make scrolling the default, edit $home/lib/profile and change every
instance of

	exec rio

to

	exec rio -s

Log out and log back in.

Think of it as making an alias or link.

Delete the namespace by closing the window.

You just found a bug; congratulations.
