AFAICT sensors isn't supposed to stick around.  This is reflected
properly in it's systemd unit file by it being configured
"Type=oneshot".

"man sensors" says the following about the "-s" switch:
"Evaluate all `set' statements in the configuration file and exit. You
must be `root' to do this. If this parameter is not specified, no
`set'  statement is evaluated."

modprobe is completing successfuly, as is "sensors -s", so everything
should be copacetic.
