Package: sysvinit
Version: 2.57b
Debian: 0.93
Kernel: 1.2.13
libc: 4.6.27
The man page for inittab(5) specifies that init looks at the file
/etc/powerstatus to determine why init received a SIGPWR (either FAIL if
a UPS signals a power outage or OK if a UPS signals that power is back).
Hence, daemons that monitor a UPS write FAIL or OK to /etc/powerstatus
before sending init a SIGPWR.
In fact, sysvinit (2.57b) looks at the file /var/log/powerstatus to
determine the nature of a SIGPWR.
Therefore, the following things could be done to "fix" this.
EITHER
(1) Update inittab(5), then hack the power daemon to write to
/var/log/powerstatus rather than /etc/powerstatus
OR
(2) Hack sysvinit to look at /etc/powerstatus rather than
/var/log/powerstatus (edit paths.h in the sysvinit source)
and then recompile init.
Option (1) is probably the easier of the two.
