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

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 total 16K drwxr-xr-x. 4 root root 4.0K Jun 12 07:06 . drwxr-xr-x. 3 root root 4.0K Mar 19 09:35 .. drwxr-xr-x. 9 root root 4.0K May 7 14:33 powerkvm lrwxrwxrwx. 1 root root 36 May 7 14:32 powerkvm-licenses -> /usr/share/doc/pkvm/licenses drwxr-xr-x. 6 root root 4.0K May 7 14:33 seprovider I've tracked the problem down to the function 'ext2_copy_file' in src/ext2fs-c.c Thanks, Daniel
