Hello
OpenBSD 4.0, i386, trying to copy from a 2007 Gentoo Linux.
I made sure there is kern.emul.linux=1 in /etc/sysctl.conf and the machine is
rebooted. Then I installed the Redhat package. Then I wanted to make the "yes"
program work. I copied all the libraries from the Linux to /emul/linux/...:
[EMAIL PROTECTED] ~ $ ldd `which yes`
linux-gate.so.1 => (0xffffe000)
libc.so.6 => /lib/libc.so.6 (0xb7e37000)
/lib/ld-linux.so.2 (0xb7f65000)
There is no file named *linux-gate* so I didn't copy this one. ld-linux.so.2 is
copied, it's symlink dereference too, has the same length. The same holds for
the libc. Then I made sure ld-2.4.so, ld.so.cache and ld.so.conf
are copied and have the same length.
Now when I run ./yes in my home directory under the user clock, I get
Bad system call (core dumped). I tried under root, the same.

I checked /etc/malloc.conf on the Linux system but it doesn't exist.
Is there some extra command I have to type so that the Linux emulation
gets enabled completely?
