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
