If I may make a suggestion, /bin/mv can move files (but not directories)
accross filesystems. If we spawn it, we avoid the entire problem [this may
not work on a (future) native port to Win32/MacOS]. I think there was a
decision against this approach.
If we wish to do this ourselves, the st_dev field of the stat structure
(the one filled by stat & fstat) tells you which device (a.k.a filesystem)
the file is on. This is easy to add to support/FileInfo.[Ch]. Another
option is statfs (Linux) statvfs (Solaris, IRIX) which takes a filename
and reports the filesystem on which the file resides.
Lior.
