This has been discussed too many times before... One scenario that you
need to find things in the shadow tree is the compiler toolchain. I.e.
the a.out compiler will continue to work in the ELF environment with
In anycase, I did not write COMPAT_AOUT for general use. I wrote it to
help me transition the i386 and sparc to ELF. Maybe other ports will
find it useful when they transition, maybe not. I don't use it anymore
and I have suffered enough from the confusion of cd /usr oops. where am I?
In other words I don't care if it stays or goes, but it should not be
turned on by default. Specially now when we have the doctored ld.so.
