System: NetBSD fish-dances.eterna.com.au 1.5Y NetBSD 1.5Y (_fish_) #88: Thu Oct 25 01:04:27 EST 2001 mrg@fish-dances.eterna.com.au:/var/_fish_ i386
Architecture: i386
Machine: i386
>Description:

	a binary i have (that i do not have the sources to) no longer
	runs on my netbsd box.  i assume this is caused by lack of
	options EXEC_ELF_CATCHALL, as the binary has no NetBSD note,
	and file calls it:

ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), not stripped

	but i haven't rebuild my kernel yet to ensure... (the machine
	is busy)

	actually, this option doesn't appear to be in options(4) at all.
	i found out via other methods...

>How-To-Repeat:

	upgrade netbsd.  attempt to run old binary.  lose.

>Fix:

	add a sysctl to enable the old behaviour so i don't have to
	rebuild my kernel.
