Samba mostly ignores ctime, for just the reasons you mention. But re-using ctime as create time will lead to more horrible confusion (IMHO). Easier to add a btime field to stat (or whatever you want to call it), especially as some of the filesystems already support it, the code for it exists inside Samba and is working on other UNIX-style OS'es, and for filesystems that don't support it, just return zero or -1 in that field (which we already ignore). > Of people can just use xattrs and do it all entirely in user space.
