Package: netcfg Severity: wishlist netcfg provides an option to completely disable all automatic configuration, but no option to disable ipv6 autoconfig (SLAAC) while leaving DHCP enabled. Putting ipv6.disable=1 on the kernel command line will cause netcfg to realize the network has no ipv6, but only after waiting a similar timeout for a link-local address, defeating the purpose.
Please either detect disabled ipv6 and skip those steps, or provide a command-line option to disable ipv6 in netcfg. (Context: repeatedly testing preseed installs in a virtual machine, and I don't want to keep waiting on ipv6 autoconfig timing out.)
