- name: Add nodev to /etc/fstab lineinfile: dest=/etc/fstab backup=yes backrefs=yes state=present regexp='(^/dev[\w/_-]+(\s+(?!nodev)[\w,]+)*)' line='\1,nodev' |
One of the lines from /etc/fstab that I am trying to add nodev is:

/dev/mapper/ex_sys-ex_home /home /ext4 rw,exec,auto,nouser,sync 1 2 |
