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:

/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.

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.

Many SysV init scripts need the /etc/init.d/functions script. But
this script is part of the initscripts package. As a result, the
initscripts package should always be installed into the system to
avoid errors when starting daemons. However, it makes no sense to
install the initscripts package into a systemd based image, because
what the init scripts provide has already been provided by the systemd.
On the other hand, the functions script might be still needed in a
systemd based image because other init scripts such as distcc might need
it.
The above situation leads to a natural separation of the functions script
from the initscripts package. And this patch does so. It separates the
functions script into initscripts-functions packages.

Previously, if we switch to runlevel 1 and then switch back to runlevel
5, the network interface will be brought down and the NFS service will
not be restarted correctly.
The problem is that the networking and rpcbind services are brought down
in runlevel 1 but not brought up in runlevel 5.
This patch fixes the above problem. It's based on the assumption that
in sysvinit-based system, runlevel 1 does not have networking support.
This patch adjusts some init script parameters used by update-rc.d. It
makes sure that networking starts before rpcbind which in turn starts
before mountnfs.sh. When switching to runlevel 0, 1 and 6, the umountnfs.sh
is run first before stopping rpcbind service, and the network is brought
down afterwards.

Adjust the boot sequence in sysvinit based systems.
The mountall.sh (mounting the local file system) needs to be started
before udev and bootlogd.
This patch makes mountall.sh start before udev and removes the hack of
mounting tmpfs in the udev init script.
This patch also adds some comments to the udev init script to make it
clear why we create the '/var/volatile/tmp' directory.

the checkroot.sh was not able to change the rootfs to read-only because
bootlogd was started earlier and had a file descriptor open. Lowering

In our current boot scripts, two ways are used to determine whether
the rootfs is read-only or not. One by checking the READ_ONLY_ROOTFS
value in /etc/default/rcS, the other by checking the /etc/fstab entry.
>From a normal Linux user's point of view, the way of checking the
/etc/fstab entry is preferred. However, as there are several boot scripts
that need to know whether rootfs is read-only or not, checking /etc/fstab
in each script brings too much overhead. Thus, these boot scripts
use the READ_ONLY_ROOTFS value in /etc/default/rcS.
In normal use cases, there would be no problem, as both /etc/default/rcS and
the /etc/fstab are modified at rootfs time. However, if the user changes
the mount option for rootfs in /etc/fstab to read-write, and he/she forgets
to change the value in /etc/default/rcS, there would be unexpected results.
For example, the udev-cache would still be disabled.
So at a minimal, a check for conflicting configurations between /etc/fstab
and /etc/default/rcS should be added in checkroot.sh so that there would be
reasonable warnings if users have configured the system in a non-consistent
way.

device_table.txt was once used by an init script named 'devices' to
create the basic files under /dev. However, it's no longer used now.
The devices init script has been removed, and makedevs command has been

Besides, considering the device managers and devtmpfs filesystem, this

/etc/init.d/hostname.sh does not have a graceful fallback if the
/etc/hostname file doesn't exist. Other systems such as Ubuntu and RH
will either leave the hostname in place, if a proper hostname is
already set, otherwise it will set the hostname to 'localhost' when
the /etc/hostname files doesn't exist.
As you can see we have to add some additional handling to provide this
behavior when the system's hostname command doesn't take the '-b'

- Remove symbolic link from /var/lock to /var/volatile/lock
- Add symbolic link from /var/run to /run
- Add symbolic link from /var/lock -> /run/lock

This avoids triple slashes in the generated /etc/volatile.cache to
reduce disk usage and in the output when verbose mode is enabled.
As all the paths for volatiles start with a slash, we can change
TNAME=${ROOT_DIR}/${TNAME} to TNAME=${ROOT_DIR}${TNAME}. To avoid
a double slash when ROOT_DIR is /, we strip the extra slash from
ROOT_DIR.

initscripts is generally installed on systemd-using images, but because it
specifies that /run is a symlink to /var/run managed by volatiles it totally
breaks systemd by copying/deleting /run from underneath systemd. Deleting
sockets mid-boot doesn't leave systemd in a happy place.
As this volatile reference of /run was introduced by udev 182, move it's
reference to the udev recipe. This way it will never be present on systemd
images, as systemd manages /run as a tmpfs itself.

Previously, if there's a link config item in the config file like
l root root 1777 /tmp /var/tmp
and /tmp has existed, the symlink will not be created correctly.
Another example is the /run directory. If /run directory has been
created by some recipe or script before populate-volatile.sh runs,
the symlink of /run to /var/run will not be created correctly.
This patch ensures that the system creates symlinks exactly as the
config file tells it.

For populate-volatile.sh script to run correctly both at rootfs time and
at system boot time, it needs to be aware of which situation it is now in.
We use the ROOT_DIR variable to indicate whether it is run at rootfs time or
not. ROOT_DIR being "/" indicates that this script is run at system boot time,
otherwise, it is run at rootfs time.
Also, we ignore failures when running this script at rootfs time.
For example, if ${ROOT_DIR}/var/dir1 is symlink to /var/volatile/dir1, it's
possible that the link is a dead link. So if we're going to create some file
under ${ROOT_DIR}/var/dir1, it will fail. But the failure does no harm,
because this script will always run at system boot time to set up the correct
files and directories.
