The crlmodels locker was recently moved. A few files were lost for the
reason given below by Jeff Schiller.

I suppose the previous machine (mnemosyne) or partition did not have a "ZMZ mode".
The bug is in two parts. First, she nor anyone else was told of this
new ZMZ restriction so that when she or anyone else went to edit her
files they were truncated to zero size. Second, this should not be
allowed to happen, without some kind of warning such as "read only" or
"can't overwrite..." from the system.
The immediate solution is to have someone with a quota on that
partition to copy (cp) the files and replace the UID before anyone
tries to edit them. Now
there's a third problem of identifying which files have a legal owner.
