Hi,
I've found a problem with supermin code running in an ibm_powerkvm
ppc64le distro.

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
Thanks,
Daniel
