That makes no difference:

<zmail03-admin.peak.org> [117] $ sh -x ~/nfst
+ cat /etc/redhat-release
CentOS release 6.10 (Final)
+ df .
Filesystem            1K-blocks     Used  Available Use% Mounted on
zbackups02.peak.org:/zbackups/zmail03-admin
                     5027215872 91682304 4935533568   2% /zbackups
+ rm -f x
+ touch x
+ chmod 444 x
+ ls -l x
-r--r--r--. 1 alan root 0 Feb 27 15:38 x
