dracut allows passing --mount option which mounts the specified devices.
But it does not wait for these devices to show up and mounting will fail
if devices do not show up by the time "mount" was called.
I am writing some patches to support kdump on iscsi target and I noticed
that one of the initqueue script was not called as we found the root
device and broke out of main loop.
There are two possible enancements to this patch.
- Introduce a time limited wait (rd.timeout something along the lines of
rd.retry). That will allow kdump to try to dump to a backup target if
primary targets fails to come up.
- Wait for UUID= and LABEL= to show up too. Right now kdump converts
UUID= and LABEL= to respective devices and passes /dev/* to dracut
--mount option. So I am not introducing the wait for UUID= or LABEL=
in this patch.

We should not trust cmdline passed by users, always
check the install files passed from cmdline. This restores
the old behaviour which was changed by:

This patch adds check of kernel module existance and
propagate errors to upper callers.
In case of break other callers of instmods(), this patch
adds an option '-c' to it, only when "-c" is specified
we fail, otherwise, errors are ignored.

do not require shutdown.target and final.target
After switch-root isolate to the default target. This will load the
default target in the real root after systemd deserializes.
If you unset CMDLINE to make _getcmdline re-read /etc/cmdline and
/etc/cmdline.d/*, CMDLINE_ETC and CMDLINE_ETC_D would keep their
contents.
This is a serious problem if you have (e.g.) "ip=eth0:dhcp" in
/etc/cmdline.d/net.conf, because getargs ip= will return
"ip=eth0:dhcp ip=eth0:dhcp" and then parse-ip-opts.sh will die() because
you have two configurations for eth0.
If you're using a static network config, you'll want to keep your
nameservers around when NM starts. Write DNS1 (and DNS2, DNS3, etc..)
into the ifcfg file.
Thanks to Mark Hamzy <hamzy@us.ibm.com>
and Will Woods <wwoods@redhat.com> for the patch.
Basically, s390 is the only place I've ever seen TERM=dumb, and it's too
dumb to handle '\r', so --progress-bar produces waaaaay too much output.
The normal progress meter only prints something once per second, so
that's reasonable on terminals where '\r' doesn't work.

Every time url-lib gets imported we end up making the list of handlers
longer with redundant entries. That's silly - we shouldn't add items
that already exist.
Note that this means you'll have to manipulate the handler list yourself
if you want to change the position/priority of existing handlers.
Sometimes some hook script will need to be before the cleanup hook scripts
For example dhclient killing, nfs cleanup, etc. must not happen before kdump
because it will use their fuctionalities.
So here introduce a new hook pre-pivot-cleanup, all cleanup scripts will go there.
that means pre-pivot hook is splited to two hooks pre-pivot and pre-pivot-cleanup
