You should not assume that "sensors -s" will clear the alarms. It does
for now because libsysfs reads all the attributes even when not told to,
however I fixed that in SVN last week, so starting with lm-sensors
3.0.1 (or whatever we number the next version) it won't be the case
anymore. You should run "sensors", not "sensors -s", if you want to
clear the alarms. You may need to wait for 2 seconds before you do if
the first "sensors -s" read the alarm registers (which is the case in
3.0.0, but should no longer be in 3.0.1.)

OK, fair enough. I think I'll add the optional insserv call, I guess it
cannot hurt as it is protected with the relevant conditionals. But I
want to keep sensors-detect somewhat distribution-neutral. So, if you
feel that part of the changes done to this script in Debian are general
enough, I would be happy to merge them upstream, with whatever
conditionals are needed so that it won't cause trouble on other
distributions. But I'm not forcing you either, if you want to keep the
changes in Debian to have better control over them, that's equally fine
with me. It's really up to you.
Same apply to other popular distros, BTW: changes that are general
enough will be considered for upstream inclusion.
Thanks,
