Comment 4 for bug 189390

Hi,

On checkout (and I would say branch) bzr could attempt to create
a temporary file with a random name in the source branch .bzr.
If this fails then a warning message could be printed.

A warning message doesn't stop the user from trying things later,
or stop people from adjusting permissions to allow writing. However
it does give a new user a clue as to what to do later.

However I think that fixing these error messages is a better idea.

Thanks,

James
