以前挂载puppy的sfs文件都没有问题的，难道是新版puppy的sfs文件格式变了？
ytian@ytian-desktop:~$ sudo mount -t squashfs -o loop,ro /media/disk/macpup_550.sfs /mnt/
[sudo] password for ytian:
mount: wrong fs type, bad option, bad superblock on /dev/loop1,
missing codepage or helper program, or other error
系统日志中可能有一些重要的信息，
试试用 dmesg | tail 之类的命令查看。
ytian@ytian-desktop:~$ dmesg |tail
