[Voyage-linux] no mpd package in voyage-mpd-0.9.0.iso after installation

[Admire123]

i followed the same method of 0.9-rc1 to install voyage-mpd-0.9.0 to my SD 
card, (choose "Generic PC" for profile) (using voyage-mpd-0.9.0.iso to boot 
and copy to SD card)

after successfully installation, when i boot up the voyage-mpd-0.9.0 sd card 
with my atom PC, i found that there no mpd package in the SD card, only 
voyage?? i have to install the mpd myself with command 

sudo apt-get update      
sudo apt-get install mpd

i did not have this problem in voyage-mpd-0.9-rc1.iso

is there any command or steps i missed?

Thanks for your help.
