systemd-tmpfiles-setup will fail at boot, so we suppress
the default versions of etc.conf and home.conf.

We also make sure that /var/{cache,spool} and /srv are writeable
if they exist.

getVar() now defaults to expanding by default, thus remove the True
option from getVar() calls with a regex search and replace.

Search made with the following regex: getVar ?\(( ?[^,()]*), True\)

It calls /sbin/umount to stop service var-volatile-lib. But umount is
installed into directory /bin. Correct it.

As this recipe inherits allarch, it makes no real difference whether
we are using ${PN} or 'volatile-binds'. But using ${PN} would keep
the same style with the other recipes in OE.

This recipe is designed to play a key role in a read-only rootfs
of systemd based systems. It generates service files from a template,
volatile-binds.service.in and the VOLATILE_BINDS variable.

By default, VOLATILE_BINDS takes the value of "/var/volatile/lib /var/lib\n",
which leads to the generation of volatile-var-lib.service file.
This file doesn't have any effect in a read-write system, as it
has "ConditionPathIsReadWrite = !/var/lib" in the [Unit] section.
In other words, this file only has effect in a read-only rootfs.
