 ==== Warning about modifying the rootfs ====
 Note that additions made to the rootfs are not safe during an update, as the complete rootfs is replaced during an update.

 ==== Hooks to install/run own code at boot ====
+Everything, except for information on /data, will be wiped after an update.
+Therefor, the trick to make changes & modifications survive an update, is to put files you need on /data, make them be (re-)installed automatically on startup. This section describes how to do that.
 If the files /data/rcS.local or /data/rc.local exists, they will be called early (rcS) and late (rc) during startup. These scripts will survive upgrades and can be used by customers to start their own custom software. Implementation details in [[https://github.com/victronenergy/meta-victronenergy/commit/2dbd16c560ff7cdf70b1d676c0616013169c7484|this commit]].
