Looking into / I see that /rescue is a file.

Why is this /rescue being created in /? It used to blow up and overflow the / filesystem (there were times when a 40 MB root FS was
sufficient).


What is the safe method to put /rescue elsewhere (in an area with enough
space). It also seems that it is being deleted by make world, at least I
seem to remember that putting a soft link into /rescue into / didn't
help either.

Symlinking /rescue -> / will cause exactly the problem you're seeing. (Because there is a file called /rescue/rescue, which will then get installed on top of the symlink. Boom!) Don't do that. You could probably symlink /rescue -> /usr/rescue, but that sort of defeats the purpose.

/rescue is part of a plan to reduce the size of the / partition,
though it's a somewhat involved process.  There are two key pieces:

1) Building /bin and /sbin dynamically.  This is a big space
   savings, but comes at a cost.  Namely, it's a lot easier
   to trash a dynamic /bin than the old static one.

2) /rescue contains a compact set of statically-linked executables
   (about 3MB total) that are provided to help in system recovery
   if /bin or /sbin gets damaged.

The catch, of course, is that step #2 needs to be finished first,
temporarily increasing the / partition size until #1 is done.

You have several options:

 * Disable /rescue.   Define NO_RESCUE to suppress it from
   being built and installed, e.g.,
     make -DNO_RESCUE buildworld
     make -DNO_RESCUE installworld
   Or add it to /etc/make.conf

 * Take the plunge and compile /bin dynamically.
   Define WITH_DYNAMICROOT in /etc/make.conf.

* Get a bigger hard disk. ;-)

Hope this helps,
