[PATCH v2 04/11] stop dracut 35network-manager from running nm-initrd-generator

[Coiby Xu]

kexec-tools depends on dracut's 35network-manager module which will
call nm-initrd-generator. We don't want nm-initrd-generator to generate
connection profiles since we  will copy them from 1st kernel to
kdump kernel initramfs. NetworkManager >= 1.35.2 won't generate connection
profiles if there's a connection dir with rd.neednet. For Fedora/RHEL,
this connection dir is /etc/NetworkManager/system-connections. For the
details, please refer to the NetworkManager commit 79885656d3
("initrd: don't add a connection if there's a connection dir with
rd.neednet") [1]. Before the release of NetworkManager >= 1.35.2, we
need to mask /usr/libexec/nm-initrd-generator.
