Hello there,
we are switching our OS from read/write to readonly with overlayfs.
We plan to have /etc /var and /tmp in an overlayfs, the rest will not be writable.
Usually services have no issues with this approach.
Anyhow there is a service called nv.service which runs the script under /etc/systemd/nv.sh
It is creating a bunch of links from ${LIB_DIR}/weston to ${LIB_DIR}/tegra/weston and also some to /usr/bin.
To me it looks like the script only needs to run once, but maybe I am missing something.
Is it okay to disable the service after it ran once or does it need to be run every time the system boots?
