no COMPAT_AOUT

versus

NetBSD 1.5E (SCREAM) #0: Thu Aug 10 04:03:43 CEST 2000

no COMPAT_AOUT


>Description:
	In the first machine, which is not really different in any
	obvious way from the other two in terms of kernel config,
	I get this:

 22484 ktrace   NAMI  "/usr/pkg/bin/setiathome"
 22484 setiathome EMUL  "netbsd"
 22484 setiathome RET   execve JUSTRETURN
 22484 setiathome CALL  open(0x10f0,0,0)
 22484 setiathome NAMI  "/usr/libexec/ld.so"
 22484 setiathome RET   open -1 errno 2 No such file or directory
 22484 setiathome CALL  write(0x2,0x1103,0xa)
 22484 setiathome GIO   fd 2 wrote 10 bytes
       "No ld.so
        \0"
 22484 setiathome RET   write 10/0xa
 22484 setiathome CALL  exit(0x1)

In the others, setiathome runs normally.  There is no "ld.so" to be found,
other than in /emul/aout/usr/libexec.

Has the absence of "options COMPAT_AOUT" not led to a COMPAT_AOUT-free
kernel in the slightly older kernels?   Or am I lost, clueless, whatever?
I'm pretty sure I did an rm -rf /sys/arch/i386/compile/{NLAPTOY,SCREAM}
before building the COMPAT_AOUT-free kernels...

Here's what one of them says:

  6504 ktrace   NAMI  "/usr/pkg/bin/setiathome"
  6504 setiathome EMUL  "netbsd"
  6504 setiathome RET   execve JUSTRETURN
  6504 setiathome CALL  open(0x10f0,0,0)
  6504 setiathome NAMI  "/emul/aout/usr/libexec/ld.so"
  6504 setiathome NAMI  "/emul/aout"
  6504 setiathome NAMI  "/emul/aout/usr/libexec/ld.so"
  6504 setiathome RET   open 3
       ...

>How-To-Repeat:
	Boot a kernel without COMPAT_AOUT on "EBONE", watch it not work.
	Boot a kernel without COMPAT_AOUT on "NLAPTOY", watch it work.
