you may safely reboot your system

Expected results:

No segfault

Additional info:

Booting with *no* kickstart and *no* cmdline arguments works without a problem.
 I can then do a DHCP URL (http) installation.
Comment 1 Chris Lumens 2008-01-15 19:59:45 UTC 
On tty3:

ERROR    : Error opening '/proc/net/if_inet6' to list IPv6 interfaces; No such
file or directory
CRITICAL : Can't get list of interfaces.

I don't know why it can't open that file.  The segfault seems to be a direct
result of not checking the file pointer being passed to fgets.  Patch to follow.

Whoops, in that second case I of course mean ifaces->fp6.

Should be fixed in the next anaconda build (which would be 10.4.0.22).
