With dracutsysrootdir set and foreign binaries in sysroot,
running NetworkManager --version is not possible and it may be
different than the one installed on the host.
NM_VERSION can be used to override it.

On EL8.3 the NetworkManager keep restarting even if it exits successfully while waiting for Clevis to unlock. This patch ensures NetworkManager runs only once in initrd.
Since commit ff70adf873ef ("initrd: save hostname to a file in /run"),
the initrd generator of NetworkManager parses the hostname from 'ip='
options of the kernel command line and writes it to
/run/NetworkManager/initrd/hostname.
When that file exists, set the kernel hostname.
In presence of multiple hostnames in the command line, the last one
wins. Hostnames from command line always have precedence over ones
received through DHCP. This is a bit different from the legacy network
module that gives higher precedence to the hostname (from DHCP or
command line) of the last interface that is brought up, which depends
on the udev order.
Install libnss_dns.so and libnss_mdns4_minimal.so plugins for the Name
Service Switch (NSS) functionality of glibc so that name resolution
through /etc/resolv.conf and mDNS works in the initrd.
Fixes: #772
The network-manager command line hook must install a
initqueue/finished hook to ensure that nm-run.sh is executed when
there are network connections to activate.
Fixes: #694
NetworkManager would unnecessarily bring up the devices, colliding with
further attempts to rename the devices.
This is arguably a NetworkManager bug and should eventually be fixed there.
Running NetworkManager without the connection is unnecessary regardless.
commit 5e0f8c8a4c ('network-manager: remove useless use of basename')
somewhat carelessly didn't take into account that $_i has a slash at
the end which made the result of the ## substitution be just an empty
string.
The slash was put to the end of /sys/class/net/*/ to make sure we're only
iterating directories, but it's not strictly necessary. In an unlikely case
something else than a directory appears in /sys/class/net/, we'll already deal
with it gracefully. Remove it.
This fixes the TEST-30-ISCSI test.
If the root is on network, let nm-initrd-generator create configuration
even if none was explicitly specified on the command line.
Also do the same if /tmp/net.ifaces exists, because the anaconda plugin
creates an empty file in that location in hopes that will make us
configure the network.
Look for "connection-uuid" instead of "managed" to determine the devices
that are actually activated with a connection and call the online hook.
This fixes the anaconda-net root mount, which utilizes the online hook.
