The result of mount command after first plug:
/dev/sda1 on / type ext3 (rw)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
usbfs on /proc/bus/usb type usbfs (rw)
none on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
/dev/sdb1 on /media/usbdisk type vfat (rw,nosuid,nodev,sync,noatime,fscontext=system_u
bject_r:removable_t,user=kubo)
and after umount :
/dev/sda1 on / type ext3 (rw)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
usbfs on /proc/bus/usb type usbfs (rw)
none on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
and now when I unplug and again plug this line :
/dev/sdb1 on /media/usbdisk type vfat (rw,nosuid,nodev,sync,noatime,fscontext=system_u
bject_r:removable_t,user=kubo)
is again there but no icon on the desktop.
