Remount as read write mode
Initialy, root filesystem mounted as read only mode as follows;
none on / type aufs (ro,si=e0ba4725)
/tmp and some directories are "rw" mounted as follows;
bash-3.2# mount |grep /tmp
tmpfs on /tmp type tmpfs (rw,size=411104k)
tmpfs on /var/tmp type tmpfs (rw,size=411104k)
bash-3.2#
To change the mode of the root directory to "rw", use mount command like this.
# mount -o rw,remount /
