dhclient initqueue hook fix
setup_net is scheduled in initqueue, sometimes it does not get chance to run
So the default route will not be set properly
Add a check in initqueue/finished to resolve this issue.

02caps: do not create /bin/sh link
caps.sh use !/bin/bash explictly, so no need to ln -sf bash /bin/sh
OTOH, 00dash will create the symlink /bin/sh, 99base will create it if
there's no /bin/sh symlink. It looks bad to creat /bin/sh in other modules.
If a script want to use bash as command interpreter it should use !/bin/bash
or !/bin/sh in case dash is not installed.

We do not support renaming in the kernel namespace anymore (as udev does
that not anymore). So, if a user wants to use ifname, he has to rename
to a custom namespace. "eth[0-9]+" is not allowed anymore.
The patch, acfab373 - Handle upper case MAC addresses in ifname
option,takes care of only the MAC conversion to lower case in the
interface name. But the same has to be taken care for BOOTIF also.
This patch takes care of changing the BOOTIF to lower case.
Note that sed has been used in the patch instead of tr, as it is not
compulsion to install tr by dracut in the initramfs and may not be
available always.

Subject: [PATCH] Fixed BOOTIF for converting mac addr to lowercase
This patch adds support of vlan tagged bonding, for example,
bond0.2. In case of regression, I also tested bond0 and eth0.2,
all work fine.

"brd +" is not valid for ipv6. This causes the 'ip addr add' command to
fail with the message "Broadcast can be set only for IPv4 addresses".
So: don't use "brd +" for ipv6.
Don't try to be smarter than the admin configuring the machine.
Does also conflict with other methods trying to setup the interfaces,
like cmsifup.sh from the cms module.
A bridge device with only one underlying ethernet device is almost
useless, for sure we want to support a bridge with multiple
underlying devices.
This patch adds the support by extending <ethname> in the original
bridge= cmdline to a comma-separated list of ethernet interfaces.

Depending on how the dasd_mod module was loaded, our device could have
already been marked as online or offline. We need to make the sysecho
sensitive to this and not fail if the attribute we're trying to set has
already been set.
Anaconda used arguments of the form:
ip=<ip> gateway=<gw> netmask=<nm>
for static IP configuration. So if we get a value for "ip" that's an IP
address, look for gateway= and netmask= and related args to fill in the
ip config vars.
wait_for_loginit ends the log; this is unhelpful if you're using
emergency_shell to do debugging.
Just leave loginit running. It doesn't hurt anything.
copytree() recursively copies the contents of SRC into DEST.
If DEST doesn't exist it is created; if it exists the contents of SRC
get merged into it (duplicate files are overwritten).
rd.neednet could be removed, as we can check /tmp/net.ifaces.
After this patch, kdump can bring up the NIC without
rd.neednet.

This patch adds basic vlan support in network module.
The cmdline syntax for vlan is:
vlan=<vlanname>:<phydevice>
for an example:
vlan=eth0.2:eth0
or
vlan=vlan2:eth0

In some cases (at least in mine) mount(8) is in /usr/bin/mount and
not in /bin/mount as dmsquash-live-root.sh expects. PATH is set to
/usr/bin:/usr/sbin:/sbin:/bin in that script anyway.
The legacy argument is DASD=, and the new arguments should be the same
as the arguments for populating dasd.conf. If multiple arguments are
passed we can stack them by inserting a ',' between them.
This is obviously wrong, ifenslave instead of brctl is needed for bonding.

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.

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

Qemu/KVM provides virtfs, a paravirtualised filesystem that is
implemented by running the Plan 9 folder sharing protocol over
virtio.
Make booting with root=virtfs:foobar use the virtfs filesystem
with mount tag 'foobar' as root filesystem, to allow booting
virtual machines off virtfs.
Note that this only handles 9p over virtio (i.e. virtfs), and
doesn't attempt to handle mounting 9p filesystems over TCP/IP,
for example.

Currently dracut uses lvm.conf as found in the system and modifies only
global/locking_type setting. As there's a new feature introduced - the lvmetad
daemon, dracut should disable its use as well by setting "global/use_lvmetad=0"
(patch attached).
Otherwise, there's a warning message issued:
dracut: WARNING: Failed to connect to lvmetad: No such file or directory.
Falling back to internal scanning.

Another solution could be searching in directories found at
/etc/ld.so.conf.d/*.conf or adding a new parameter. Here is a patch
which adds a new --libdirs parameter, and also a new inst_libdir_file
function which will try to expand metacharacters on each lib
directory:
inst_libdir_file "libdevmapper-event-lvm*.so"
Mounting, unmounting and then mounting a disk partition takes some
time.
On embedded systems such as OLPC XO where we disable fsck and fstab
reading, the root options are not going to change throughout the
mount_root() function, so remounting is time consuming and without
change.
Detect and optimize for this case so that the filesystem is only
mounted once.
According to its comment in dracut-lib.sh:
splitsep ":" "one:all:the:rest" one two
should set two="all:the:rest". But there's no check to see if the
current field is the last field, so it just gets "all".
For NetworkManager to properly take over a NFS-root system, we need to
have the interface name(s) in /tmp/net.ifaces and save the dhclient
lease. This lets the ifcfg module do its magic.
save_netinfo should properly write out /tmp/net.ifaces when needed, and
copies the dhclient files into place.
This makes sure the network is active and ready to use during the
initqueue/online hook.
It also makes it so you can run setup_net repeatedly without causing
error messages.
also fixup the logic what and when to mount.
first initramfs/etc/fstab is mounted
$NEWROOT/etc/fstab.sys takes precendence over initramfs/etc/fstab.sys
