I'm PXE booting, and I have "ip=dhcp noipv6" on the command line. However,
starting with F7 and up through current rawhide, I still get the "Configure
TCP/IP" screen. In FC6 and before it was bypassed because the settings were on
the command line.
The change in bugzilla #233152 looks wrong to me and I think is the source of
this. If I revert that change, I get the old behavior (no prompt for IP info
when provided on the boot command line).
This bug is also present in the RHEL 5 code base. Have been working on fixing
it there and will apply the fix to rawhide once I have that complete. Thanks
for the bug report.
