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.

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"
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
If /etc/fstab.sys does not exist installing fstab-sys module will fail.
Fix this by checking use_fstab and fstab_lines as well

Add ssh client module which support ssh key mode and interactive mode.
with --sshkey option you can provide the ssh key to be installed
>why not call it "ssh" module?
ssh-client is better, maybe future there will be ssh-server come in.
In debian these are also two different packages.
Usage:
1. sshkey mode:
transfer your public key to remote machine with ssh-copy-id or do it mannaully
example of options:
./dracut -l -H -a ssh-client --sshkey /root/.ssh/id_rsa i.img
2. interactive mode:
need use --ctty option, ie.:
./dracut -l -H -a ssh-client --ctty i.img
[v2 changes]:
per wangcong: add patch description about module name
add help line in usage()
remove useless comment

Option --ctty will optionally add setsid binary to dracut's image.
During runtime, if rd.ctty is set and is a character device,
emergency shells will be spawned with job control.
in case no ctty was provided, shell was spawned without caring about
/dev/console. Also, the ctty is more opportunistic. If the image was
generated with --ctty, we will fallback to /dev/tty1 if rc.ctty is
invalid or missing. Otherwise we spawn standard shell on /dev/console

Like -H, we need to poll every module to check if it is needed
to mount a specific device in '--mount'.

Don't force --mount only working in hostonly mode, let users decide.
With this patch, people can still combine -H --mount '...' if they
want to use it in hostonly mode.

--add-fstab [FILE] Add file to the initramfs fstab
--mount "[DEV] [MP] [FSTYPE] [FSOPTS]"
Mount device [DEV] on mountpoint [MP] with filesystem
[FSTYPE] and options [FSOPTS] in the initramfs
Determine devices and filesystems to be included in the host-only
initramfs image.
To get a minimal initramfs, which can mount
/
/etc
/usr
/usr/bin
/usr/sbin
/usr/lib
/usr/lib64
/boot
we look in fstab for the corresponding devices and determine their and
their slaves' filesystem type and put all that in $host_fs_types
and $host_devs.
