In the current state, services that depend on network need to
use dracut hooks, since nothing with pull in the network
targets into the transaction.
In the future, it would be nice to provide developers on systemd-only
systems the possibility to not use dracut hooks at all, but simply put
normal systemd services into the initrd.
Also, some modules even right now depend on systemd ordering, like
cryptsetup, so let's make sure, that the ordering inside systemd work
properly as well.
Previously if "$rootok" = 1, parsing of netroot command line arguments
was skipped. For multiple netroot arguments, all parse scripts have to
run.
Previously only the first netroot argument was taken into account for
the parsing scripts. Now every netroot argument is processed.
For NetworkManager to properly take over a NFS-root system, we need to
have the interface name(s) in /tmp/net.ifaces and save the dhclient
lease. This lets the ifcfg module do its magic.
save_netinfo should properly write out /tmp/net.ifaces when needed, and
copies the dhclient files into place.
Add new functions: all_ifaces_up, get_netroot_ip, ip_is_local, ifdown,
setup_net, set_ifname, ibft_to_cmdline
Use them in netroot.sh and parse-ip-opts.sh.
There's also a couple little unrelated cleanups.
