So, our mythical system library (libundelete.so) should support a couple of generic functions (say: int safe_unlink(const char *path), and void empty_recyclebin(const char *path) which look for an ENV variable to determine if they should recycle or should delete, as appropriate) for applications to call, and then the library code has to support implementing this on various FSes.
If it were unlink(3C) rather than unlink(2), an interposer library could make this functionality generally available. Surely there must be a dtrace hack that could redirect calls destined for unlink() to safe_unlink(), subject to environment information. I suspect, however, that protecting every file from deletion may be a bit aggressive. Consider "here documents" from shell scripts, browser cache files, compiler temp files, etc. Mike -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
