Package: coreutils
Version: 5.93-5
Severity: normal
mounted partition is as follows:
lipn-sf4:/export/vol01/jcdubacq on /users/jcdubacq type nfs (rw,addr=10.10.0.14)
Experimentation:
[EMAIL PROTECTED]:~$ cd /tmp/
[EMAIL PROTECTED]:/tmp$ cp -p /etc/ssh/ssh_config .
[EMAIL PROTECTED]:/tmp$ ls -l /etc/ssh/ssh_config ./ssh_config
-rw-r--r-- 1 root root 1379 2005-09-16 11:41 /etc/ssh/ssh_config
-rw-r--r-- 1 jcdubacq ocad 1379 2005-09-16 11:41 ./ssh_config
[EMAIL PROTECTED]:/tmp$ cd ~ # NFS partition
[EMAIL PROTECTED]:~$ cp -p /etc/ssh/ssh_config .
[EMAIL PROTECTED]:~$ ls -l /etc/ssh/ssh_config ./ssh_config
-rw-r--r-- 1 root root 1379 2005-09-16 11:41 /etc/ssh/ssh_config
-rw-r--r-- 1 jcdubacq ocad 1379 2006-02-02 17:25 ./ssh_config
[EMAIL PROTECTED]:~$ touch -r /etc/ssh/ssh_config ./ssh_config
[EMAIL PROTECTED]:~$ ls -l /etc/ssh/ssh_config ./ssh_config
-rw-r--r-- 1 root root 1379 2005-09-16 11:41 /etc/ssh/ssh_config
-rw-r--r-- 1 jcdubacq ocad 1379 2005-09-16 11:41 ./ssh_config
So touch -r works fine, but not cp -p. Things get weirder when doing
straces:
----- strace for cp -p /etc/ssh/ssh_config . with . = NFS -----
