When booting from an initrd disk, or when the kernel config option
DEVTMPFS_MOUNT isn't provided, /dev/ will not be mounted at boot.

This small addition will check if /dev/ is "useful", and if not, will
mount devtmpfs if the kernel provides it.

With this change, it is possible to set an initscripts style image type
to "cpio.gz" and boot it as initrd. Without this change, the image won't
work properly because of the missing devices.

It is not possible to create a rootfs with only busybox + initscipts.
This is a result of a regression from commit
a4b53872a8a9a2743299acbff015f7f2750a69d6 (initscripts: add
/sbin/sushell for systemd service debug-shell).

The /sbin/sushell should just use /bin/sh else you end up with a
problem when creating the end image with a failed smart transaction
shown below:

Add file /sbin/sushell for systemd service debug-shell which starts with
/bin/sushell when SELinux is enabled. Copy and add sushell file from
Fedora 22.

Add runtime dependency bash as well when systemd is enabled to eliminate
QA warning:

WARNING: QA Issue: /sbin/sushell_initscripts contained in package initscripts

/etc/volatile.cache is a cached copy of a script (which is
generated by /etc/init.d/populate-volatile.sh) that generates
the volatile filesystem directories.  Since volatile.cache is
a generated file, it is not necessarily changed if
populate-volatile.sh is updated.  As a result, the stale script
can add/remove the wrong directories on the next system boot.

If initscripts is being upgraded, make sure volatile.cache gets
deleted.

After removal of auto-creating S we must ensure that all recipes are
using a proper value for S.

Fix all recipes that only need to set S equals to WORKDIR.

Use CONFFILES to mark editable files as such,
  /etc/init.d/checkroot.sh

If there is no %config micro before the file name in the spec file,
this file will be overwritten after updating package.
This will make our settings lost.

We now support executing scripts under /etc/rcS.d. So we need to
mask several more init scripts here to prevent them from running
at boot time.

In the commit 'initscripts: save /etc/timestamp with seconds accuracy',
a bashism was introduced in the bootmisc.sh script in the code to set
the current date from the stored value in /etc/timestamp.  This causes
that operation to fail with the following message when /bin/sh is not
bash:

/etc/init.d/rc: /etc/rcS.d/S55bootmisc.sh: line 73: syntax error: bad substitution

Fixed by using pattern matching removal rather than bash-specific
substring expansion.
