Hi,
/sbin/upsdrvctl is used as the near final step in /etc/init.d/halt

the UPS to shut down power to the computer. On Fedora / Red Hat
Enterprise
Linux system, /usr can reside on its own partition.
Would it be possible to remount /usr read-only at shutdown?
Drivers are linked to several libraries, but some of them lives in /
usr/lib
and this can be umounted when drivers are used. There are 16
libraries used on
Fedora 11 system. This prevents nut to properly shutdown ups.
I think all of the libraries used by the NUT drivers are in /lib on
Debian, but Arnaud can give you more details.
The 16 libraries might be an upper bound of what is actually being used:

How is this designed to work? Is it expected all drivers are linked
statically? 16 libraries does not seem to me as unexpectedly placed to
/usr/lib instead of /lib
Not sure I understand the "unexpectedly placed" part.
