Hi,
I've found a problem with supermin code running in an ibm_powerkvm
ppc64le distro.
Output of libguestfs-test-tool:

This is how the filesystem looks like. It seems that supermin tries
to copy the contents of
powerkvm-licenses, which is a link to /usr/share(...) and then it
has problems when returning
to the parent dir /opt/ibm .
$ cd /opt/ibm
$ ls -lah

I've tracked the problem down to the function 'ext2_copy_file' in
src/ext2fs-c.c
You might want to check if it works with the upstream supermin.
(Perhaps d7bb984889257f5b87963dcca6456fc6e4cc804e fixes it?)
However probably the easiest thing to do is to add /opt/ibm and
perhaps /opt/ibm/powerkvm and maybe /usr/share/doc/pkvm/licenses to
the appliance. Something like this:
cat > /usr/lib64/guestfs/supermin.d/00-directories <<EOF
/opt
/opt/ibm
/opt/ibm/powerkvm
/usr/share/doc/pkvm/licenses
EOF
