Let me see if I have this right - /home is mounted as part of /, and
not as a seperate partation. And when home is gone, the /home directory
is missing, not just empty?
If I have this right, it sounds like someone renamed home, and/or moved
it so it is a subdirectory of another directory. This can be done with
vary littel disk activity.
Now, if /home is still there, but empty, could someone have mounted an
empty partation on top of home? That would make the contence of home
vanash without realy removing them.
In any case, check the output of the df command, and see if the space
used on the disk is changing enough for the files to have actualy
ben erased. I am not sure if df will show partations mounted using
mount -n, but I think mount will.
