This is the problem I want to address. Would it not be possible
to add to the error image the following message: "Dir b/a already
exists" or something similar making the real problem clear right
from the start?
Like I said earlier, POSIX allows either ENOTEMPTY or EEXIST, and
Linux
happened to choose ENOTEMPTY. Maybe special-casing that error and
converting to EEXIST would produce better output. But someone would
have to submit a patch.
Sorry, I can't submit a patch, it's beyond my capabilities.
I have submitted the problem, and consider my job done.
Thanks for the reply,
Best regards,
Francky
