OK, but, the original message at
<http://bugs.gentoo.org/show_bug.cgi?id=132673> points out a real
problem.  However, the problem does not occur with me, so it most
likely is a bug in his NFS implementation (perhaps the gentoo NFS
client code?).

Here's an example of cp -p working on Solaris 8 (sparc) with an
NFS-mounted file:

1017-kiwi $ cp --version | head -n1
cp (GNU coreutils) 5.94
1018-kiwi $ truss -o tr cp -p /etc/motd motd
1019-kiwi $ tail tr
read(3, " S u n   M i c r o s y s".., 8192)     = 59
write(4, " S u n   M i c r o s y s".., 59)      = 59
read(3, 0xFFFFFFFF7FFFC000, 8192)               = 0
utimes("motd", 0xFFFFFFFF7FFFADF0)              = 0
fchown(4, 0, 3)                                 Err#1 EPERM
close(4)                                        = 0
close(3)                                        = 0
close(1)                                        = 0
lseek(0, 0, SEEK_CUR)                           = 7678
_exit(0)
