[PATCH] Prevent segfault when network install method fails in loader.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Happens at least for NFS installs, but if we fail to mount and present
the failure newt window and the user chooses Retry, loader segfaults.
If loaderData->method is -1, we need to force them back through the
network configuration stages (which is part of a fix for an older bug
that would prevent users from changing the network settings if the
network install method failed).
