[Bug 57317] dapper cp -p does not preserve date over nfs

[Mattias Wadenstein]

Public bug reported:

Binary package hint: fileutils

Using fileutils 5.93-5ubuntu4 in dapper, in an nfs mount (we've tried
both linux and solaris nfs servers, same result):

h5n1:~/test> ls
h5n1:~/test> touch foo bar
h5n1:~/test> echo muu > baz
h5n1:~/test> ls -l
total 8
-rw-r--r-- 1 maswan adm 0 Aug 22 18:45 bar
-rw-r--r-- 1 maswan adm 4 Aug 22 18:46 baz
-rw-r--r-- 1 maswan adm 0 Aug 22 18:45 foo
h5n1:~/test> mkdir nu
h5n1:~/test> date
Tue Aug 22 18:48:01 CEST 2006
h5n1:~/test> cp -p bar baz foo nu/
h5n1:~/test> cd nu
h5n1:~/test/nu> ls -l
total 8
-rw-r--r-- 1 maswan adm 0 Aug 22 18:45 bar
-rw-r--r-- 1 maswan adm 4 Aug 22 18:48 baz
-rw-r--r-- 1 maswan adm 0 Aug 22 18:45 foo


Note that "baz" got a new date, despite being copied by cp -p. This does not affect local filesystems as far as we can find. Interestingly enough the 0-byte
files get their date preserved, but not files with content.
