When you execute programs with wine, it just reads ("copies") the file from the mounted NTFS volume, so that would not make any difference. You'd basically have to implement a more general way to control _reading_ access to files. With the basic mount options, that isn't really possible. Also note that for certain programs, it's not sufficient to just copy a binary and run that. Libraries and other resource files might be involved. However, a "local installation" in ~/.wine/drive_c would be possible. > Note that I cannot enable this behavior with '-o noexec' : that only > disables > execution of binaries by the kernel itself, not the emulation layer - > which just > needs read access. Correct. "Windows" programs aren't executed in a manner that it would be triggered by the -noexec mechanism. > Is it possible for me to achieve that behaviour ?
