++ readlink -f dump/unlink_fstat02/1571/1
+ ddump=

# readlink -fm dump/unlink_fstat02/1571/1
/root/git/criu/dump/unlink_fstat02/1571/1

The -m option is required if a target doesn't exist.

I think we need smth like this:
diff --git a/test/zdtm.sh b/test/zdtm.sh
index 6729b91..990ea72 100755

Thanks.
