Extract A Squashfs To An Existing Directory
Solution 1:
The source you link to tells you what you need to do:
The tool does not extract a squashed file system on already exsisting directory unless the -f option is specified.
So this should work
sudo unsquashfs -f -d /media/location1 /media/location2/file.squashfs
Solution 2:
-
Mount the squashfs FILE.SQUASHFS :
sudo mount -t squashfs PATH/TO/FILE.SQUASHFS /mnt -
Copy his content to DIRECTORY (must exist) :
sudo cp -av /mnt/. PATH/TO/DIRECTORY -
Unmount the squashfs FILE.SQUASHFS :
sudo umount /mnt
