>Release: FreeBSD 3.1-RELEASE i386
>Organization:
Dignus, LLC
>Environment:
3.1R and 3.2R installation via direct SL/IP line.
>Description:
There is a bug in the ifconfig of the slip interface.
If you slattach a slip unit to a tty _before_ doing the
`ifconfig slX', the ifconfig will fail with EEXISTS.
(see PR kern/12251 for more information.)
Unfortunately, that's the order sysinstall takes for
the SL/IP connection.
Doing the ifconfig followed by the slattach should work.
>How-To-Repeat:
Try to do a SL/IP install.
>Fix:
The following is the context diff to 3.2-R's
/usr/src/release/sysinstall/network.c to move the
slattach after the ifconfig. That should be an
adequate "work-around" until some solution for the
kernel bug is found.
