Suppose you are logged into your Android device using adb or perhaps by means of a console app, and you require write access to /system then do as following
Become root
# su
Check how the /system partition is mounted as read-only (ro), In particular note the device
# mount | grep system
/dev/block/stl12 /system ext4 ro,relatime,barrier=1,data=ordered 0 0
Remount the partiton in read-write mode (rw)
# mount -o rw,remount /dev/block/stl12 /system
Finally check if it was mounted in read-write mode (rw)
# mount | grep system
/dev/block/stl12 /system ext4 rw,relatime,barrier=1,data=ordered 0 0
When done, do not forget to remount it read-only again, for safety reasons, obviously
# mount -o ro,remount /dev/block/stl12 /system
