live.updates allows you to specify the URL for an "updates image" that
should be applied to the live runtime before switch_root.
The URL can be anything supported by url-lib (http, https, ftp, possibly
nfs) and the image can be anything supported by img-lib (xz/gzip
compressed cpio/tar, uncompressed cpio/tar, filesystem image, etc.)
For curl_fetch_url (http/https/ftp):
- use --progress-bar (the output is less messy)
- print the URL we're fetching so the user know's what's happening
For curl and nfs:
- don't echo the filename if it was provided by the user
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.
