hello,

i've repeated the installation process. my partman preseed setup 
contains separate partitions for
     /
     /boot
     /usr
     /var
     /tmp

with this setup, issuing the command 'upsmon -c fsd' stops the server 
but does not make the ups 'reboot' the output outlets.

i've repeated the installation without a separate partition for /var (so 
/var is contained in / partition) and the result is the same. so /var 
seems not to be the problem.

i've repeated the installation without a separate partition for /usr (so 
/usr is contained in / partition) and the result is that now it works: 
the server is stopped and the ups is 'rebooted'.

i did all these tests using the default systemd, and also replacing it 
with sysvinit. the results were the same independently of the init 
system used.

looking at my /etc/rc0.d, nut client and server have number 01 and 
filesystems (not root) are unmounted at 06, root is unmounted at 07 and 
finally in 08 system is halted / poweroff.  these numbers depend on the 
services installed on the system, but the order should be the same. if 
/usr is in a separate partition, it is unmounted at 07 (and 
"disappears"). if it is within /, in 08 it is still there because root 
is not unmounted, it is just mounted read-only.

i think the problem is that the nut stop scripts does not trigger the 
ups reboot *before* finishing and before the stop system pass to the 
next level. the process to trigger the reboot is done in parallel with 
the system shutdown and if /usr is gone it fails to reboot the ups.

what do you think? am i wrong?

thanks.
