Maybe mention that ->sun_path in struct sockaddr_un is UNIX_PATH_MAX

Works for me. Perhaps the UML people can figure out what's going on.

Aah, you're absolutely right. I was missing /dev/tty[1-6] device nodes.

Hi,
I have a problem with UML compiled from 2.6.18-rc2 git head. The kernel
boots fine and starts up the userspace but hangs completely after
forking gettys. I have port-helper in /usr/lib/uml but it doesn't seem
to start up.
The host is Ubuntu Dapper Drake running on Intel Core Duo.
Hi,
UML in 2.6.16-rc1-git4 fails to boot a Debian 3.0r2 image. The same
image works boots properly with 2.6.15. Here's the error:

Checking that ptrace can change system call numbers...OK

Hmm. Somebody broke UML compile for my config again...
CC arch/um/sys-i386/stub_segv.
undeclared identifier is reported
only once
arch/um/kernel/tt/uaccess.c:11: error: for each function it appears in.)
The error only happens when I disable CONFIG_MODE_SKAS.
