I think it may depend to some extent on what software you are using to
connect to the NAS drive - you don't say.
Software like !Lanman98 and !FTPc will automatically convert illegal
characters, eg slash and dot are swapped.
Under Linux the slash is the folder separator so an unconverted filename
starting with a slash is not recognised.
However a hidden file under Linux starts with a dot so a Linux file copied
to RISC OS with conversion would start with a slash as in your /cvsignore
above but when you try to copy it back the software you are using is not
converting it back to a dot on the Linux system.
As I don't have a NAS drive I don't think I can do any more to help at the
moment. But the above may be a pointer to the solution of the problem.
