"/etc/init.d/pxe stop" loops, waiting for pxe.pid to disappear before exiting.
On my system /usr/sbin/pxe died for some reason, leaving around a stale
/var/run/pxe/pxe.pid. That causes /etc/init.d/pxe to loop indefinitely.
/etc/init.d scripts that loop can have a variety of nasty side effects, like
preventing the system from shutting down cleanly and causing logrotate to fail.
A simple fix it to make the wait_no_pid() in /etc/init.d/pxe check to
see if /var/run/pxe/pxe.pid is stale, and remove it if it is. Here is
a new version of wait_no_pid() to do that. Replacing the existing
wait_no_pid() in /etc/init.d/pxe with this version will resolve this bug
report.
wait_no_pid()
{
local pid=$(cat "${PID}" 2>/dev/null) || return 0
local exe=$(readlink "/proc/${pid}/exe" 2>/dev/null) || :
while [ "${exe}" = "${DAEMON}" ]
do
sleep 1
pid=$(cat "${PID}" 2>/dev/null) || return 0
exe=$(readlink "/proc/${pid}/exe" 2>/dev/null) || :
done
rm -f "${PID}"
}
