WHEN USB FLASHDISK INSERTED AND MOUNTED BY UDISK-GLUE

Supervisord continously run minidlna_scanmedia.sh until it recognize there is usb disk mounted on /media/SLAX9.4, it will run "service minidlna force-reload" and then clear "/var/log/supervisor/udisks-glue-out.log" so it becomes empty

#*******************************************************************************
#ACTION !
#*******************************************************************************
root@raspime:~# mount | grep media

/dev/sdb1 on /media/SLAX9.4 type fuseblk (rw,nosuid,nodev,noatime,sync,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096,uhelper=udisks)


root@raspime:~# cat /var/log/supervisor/minidlna_scanmedia-out.log

Successfully automounted /dev/sdb1 at /media/SLAX9.4
Thu 6 Dec 20:31:43 WIB 2018
mounted media successfully and minidlna will force-reload

The script will then clear udisks-glue-out log

root@raspime:~# cat /var/log/supervisor/udisks-glue-out.log
** EMPTY **
