The "online" hook runs whenever a network interface comes online (that
is, once it's actually up and configured).
The initqueue --env argument is used to set "$netif" to the name of the
newly-online network interface.
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.
Since cp won't copy a directory over a symlink, any updates that were
supposed to go into e.g. /lib would get dropped if you had /updates/lib
as an actual directory, but the target system had /lib->/usr/lib.
As described in https://bugzilla.redhat.com/show_bug.cgi?id=541410#c2,
if you want NetworkManager to take over an interface that you're using
for NFS root (or other network root device), you need to:
a) set UUID=<uuid> in ifcfg-<iface>, and
b) save the lease file as /var/lib/dhclient-<uuid>-<iface>.lease
This patch should make write-ifcfg handle both these things.
first check for omit, then mark the kernel module as seen
when we temporarily omit_drivers, we don't want to mark them as seen.
example: nfs.ko module in kernel-modules, but the nfs module
should be able to load it later on.
In kernel_only mode, we don't want to write /etc/cmdline.d
Correctly return the check functions, so we have a valid return of
for_each_host_dev_fs().
mdraid and dmraid functions had wrong checkings for the filesystem
type.
Due to the way the main loop runs to detect partions, the same one
might be included twice (albeit via different symlinks.
This code simply prevents the same combo being activated twice.
A better fix might simply be to not include duplicate (after
resolving symlinks) entries in the host_fs_types variable.
