--persistent-policy <policy>:
Use <policy> to address disks and partitions.
<policy> can be any directory name found in /dev/disk.
E.g. "by-uuid", "by-label"
This prints the kernel command line parameters for the current disk
layout.

We only wait for master interfaces for bridge/bonding/team/vlan case.
If none of these complex network is configured, we should wait for
ethernet interface (bootdev) instead.
systemd uses vt102 as default term for tty:

default to v102 everywhere, instead of vt100, to synchronize with agetty

Currently when action_on_fail is enabled, the emergency_shell won't be called.
In kdump even though user specify the default action as emergency_shell,
dracut skip it. Now change the implementation of action_on_fail to depend
on a file which is created by kdump when making kdump initrd, then remove it
at the beginning of kdump. This can solve the explicit emergency_shell problem.
And action_on_fail won't need paramenters, remove the relevant description in
dracut man page.

To eliminate a race condition that occurs when unlocking one device
depends on the result of unlocking a device before it, the crypt
module must wait for udev to settle between each unlock attempt.
Example
/etc/crypttab:
keyfile /dev/md1 none luks
sda4_crypt /dev/sda4 /dev/mapper/keyfile luks
sdb4_crypt /dev/sdb4 /dev/mapper/keyfile luks
Without this patch, sometimes /dev/sda4 fails to unlock because udev
doesn't have time to create /dev/mapper/keyfile before it's needed.
Prevents following error message:
I: *** Including module: crypt ***
/usr/lib/dracut/modules.d/90crypt/module-setup.sh: line 31: /etc/crypttab: No such file or directory
kernel-tegra is now part of the base kernel package, so bits and pieces
ended up modular, and as a result, if you boot off the internal USB, you
drop to a dracut shell with no way of getting to root.
