Discussion related to cado-nfs

Hello, all.  I have been factoring a ~c155 for a few days and it
failed last night on the linear algebra step.  It seems my /tmp had
too little space for it to do the work.  As an attempt to remediate
that, I moved the directory out of temp and onto a partition with
plenty of space.  I placed a symlink from /tmp to the new location.

Upon restarting the cado-nfs.py script with the location of the
recovery parameter file, I was told that there was a short read from
the .prep file.  Moving that out of the way and restarting resulted in
the same error.

My question is how to recover from this and restart from the last good point?

Thank you for your work on this wonderful tool.  I'm afraid I've been
out of factoring for the last decade and I'm not fully up to speed on
the current crop of tools.

Cheers,
David Willmore
