hi,I am confused with a problem about nALFS. How can I identify those packages installed in order to exclude them when I restart nALFS? Refer to ~/.nALFSrc, "stamps" directory seems have this function with <check>. However, it doesn't work. What's more, I cannot find "<check>" in my profile! Why? Must I remember the nALFS progress manually?! Help me please,thanks.
