genisoimage: No such file or directory. Invalid node

genisoimage: No such file or directory. Invalid node

I've found and fixed this before and forgotten how.

When ripping CD/DVD whatever one gets the mystery error:

"genisoimage: No such file or directory. Invalid node"

And/or the more puzzling:

"input-charset not specified, using utf-8"

mkisofs, genisoimage, etc all give the same error, and from what the forums
say no one has a clue what to do about it.

Although the error message is utterly useless the cause is very simple.
mkisofs, genisoimage, etc are unhappy about /tmp, I expect it's a space
issue, whatever, just delete /tmp/kde-user and ln -s it off to a larger
filesystem.  Or change the app settings to use another tmp location.  Or the
much harder route of increasing /tmp size.
