What were you trying to do?
"Save a Copy" of a file to a USB flash drive mounted with attach-usb.
What's wrong:
Acroread complains that I am not a superuser, even though other
programs can save to /mnt/usb just fine (for example, mozilla,
or touch'ing a file at the command prompt). Acroread still makes
this complaint if I run it as the superuser, which would probably
indicate this is a bug rather than a legitimate error.
What should have happened:
The file should have been saved.
Please describe any relevant documentation references:
Here is what I think is a relevant chunk of an strace performed
when running acroread as cda:
