Description:
If pulseaudio is running system-wide, the volume levels of all applications will not be restored (they will be at 100%) when you reboot your machine.

Steps to reproduce:
1) start pulseaudio with the init script
/etc/rc.d/pulseaudio start
2) launch an application using pulseaudio
3) change the volume level to a specific value (can be checked by pavucontrol)
4) stop the application
5) restart pulseaudio
/et/rc.d/pulseaudio restart
6) relaunch your application using pulseaudio (the volume level is correct)
7) reboot the machine
8) start pulseaudio with the init script
/etc/rc.d/pulseaudio start
9) relaunch your application using pulseaudio
the volume is incorrect !

The volume table file needed to restore the volume levels is stored in /var/run/pulse/volume-restore.table but the initscript rc.sysinit removes leftover files from /var/run at startup
/etc/rc.sysinit:359
(cd /var/run && /usr/bin/find . ! -type d -exec /bin/rm -f -- {} \; )

Additional info:
* package version(s)
- pulseaudio 0.9.10-1
- initscripts 2008.03-4

Fix:
In the file /etc/pulse/default.pa you can specify where to save the table to restore volume level:

load-module module-volume-restore table="/var/lib/pulse/volume-restore.table"
