+By default, the rootfs is mounted read only. Also, by default, it only has 5% of free space, while the partition in which its installed is actually larger.
-The solution is to run ''/opt/victronenergy/swupdate-scripts/resize2fs.sh''.
+The recommended method to **(a)** mount it as read/write, and **(b)** expand it to use all of the available space in its partition, is by running ''/opt/victronenergy/swupdate-scripts/resize2fs.sh''.

+  * //semi-permanent//: issue the command ''/opt/victronenergy/swupdate-scripts/remount-rw.sh'' (which holds until the next firmware update)
+  * //permanent//: adding one of the above commands to ''/data/rc.local'' (which holds permanently)
