8425	[filesystem][documentation] copy_file cannot overwrite executing binary	boost@…	Beman Dawes	"If trying to copy a binary file over the currently executing program, then the ''copy_file'' call fails even though it has the ''overwrite_if_exists'' flag.

Examining the code, this appears to be because ''copy_file_api'' (Linux) uses popen, thus attempts to write to the same file data as distinct from creating a new file node.

The peculiar error ""Text file busy: <binary>"" is reported.

Given that the Windows version would not (AFAIK) be able to achieve this anyway, I would say that this behaviour is ""by design"" but suggest a documentation update for ''copy_file''.
