Understanding df output on Jolla 1 for btrfs filesystems

Hi,

I'm using a Jolla1 and I have two questions :

Can someone explain the multiple lines of df output for the /dev/mmcblk0p28 partition ?

$ df -PTh | grep /dev/mmcblk0 | grep /opt
/dev/mmcblk0p28 btrfs   14G  8.9G  4.3G  68% /opt/alien/data
/dev/mmcblk0p28 btrfs   14G  8.9G  4.3G  68% /opt/alien/bin
/dev/mmcblk0p28 btrfs   14G  8.9G  4.3G  68% /opt/alien/sbin
/dev/mmcblk0p28 btrfs   14G  8.9G  4.3G  68% /opt/alien/lib
/dev/mmcblk0p28 btrfs   14G  8.9G  4.3G  68% /opt/alien/usr
/dev/mmcblk0p28 btrfs   14G  8.9G  4.3G  68% /opt/alien/var
/dev/mmcblk0p28 btrfs   14G  8.9G  4.3G  68% /opt/alien/etc
/dev/mmcblk0p28 btrfs   14G  8.9G  4.3G  68% /opt/alien/home
/dev/mmcblk0p28 btrfs   14G  8.9G  4.3G  68% /opt/alien/vendor
/dev/mmcblk0p28 btrfs   14G  8.9G  4.3G  68% /opt/alien/media
/dev/mmcblk0p28 btrfs   14G  8.9G  4.3G  68% /opt/alien/system_jolla

Where are those mount point directories defined in the system ?
