How to show the free space left in slxsave.xfs

[dekarma]

I have to boot my salixlive-xfce-13.1.2.iso without changes=slxsave.xfs:
label salixnp
menu label Salix non-persistent
kernel /salix/vmlinuz
append initrd=/salix/initrd.gz root=/dev/ram0 rw from=/salix/salixlive-xfce-13.1.2.iso
Then I have to: mount -o loop slxsave.xfs mytmpdir
and the df-command shows the free space left.

Is there a way, when booting with changes=slxsave.xfs?
Neither "df -a" or "/sbin/losetup -a" helps,
nor was my googleing or search in StartUpGuide or Forum successful.

I guess mount -o loop.ro slxsave.xfs mytmpdir; df -a should work
