Greetings list,

I have just figured that NFS since version 4.2 is capable of transferring m=
andatory access lists (i.e. SELinux labels) and hoped it would be also able=
 to transfer birth time (as of the statx() kernel interface) as an addition=
 to the standard POSIX atime,mtime and ctime.
Unfortunately it does not seem to work (tried with Fedora 35).

Hence my question, is such a feature considered to be implemented at some s=
tage?
Thanks,
Ondrej
