Re: Bug#633423: Problem with autofs 64-bit kernel/32-bit userspace compatibility



reassign 633423 linux-2.6
retitle 633423 autofs4 interface is broken between x86 and x86_64
affects 633423 systemd
thanks

Short summary for readers new to the bug: boot hangs with i386 systemd
and an x86_64 kernel.

Thankfully this problem has now been communicated to Linus himself, and
he agreed that it should be fixed in the kernel.  See the following long
threads on the LKML:

http://thread.gmane.org/gmane.linux.kernel/1255125
http://thread.gmane.org/gmane.linux.kernel/1256405

I will keep an eye on this bug and send an update when a fix appears in
Linus' tree that I can test.

Cheers,
       Sven
