The configuration is taken from /proc/cmdline, aiming at emulating the
behavior of the kernel when no initramfs is used.
The supported options are: root=, rootfstype=, rootwait=, rootflags=,
ro, and rw. rootdelay= was dropped, as it is not really useful in a
systemd world, but could easily be added.
v2: fix comments by Lennart, and complain loudly if root= can not be found

If the path to init is not specified as an argumnt to systemctl, but
init= is given on the kernel commandline, use that.
This means the initrd does not need glue code to parse the kernel
commandline before passing on init= to systemctl.

For many usecases it is useful to store the chassis type somewhere, and
/etc/machine-info sounds like a good place. Ideally we could always
detect the chassis type from firmware, but frequently that's not
available and in many embedded devices probably entirely unrealistic.
This patch adds a configurable setting CHASSIS= to /etc/machine-info and
exposes this via hostnamectl/hostnamed. hostnamed will guess the chassis
type from DMI if nothing is set explicitly. I also added support for
detecting it from ACPI, which should be more useful as ACPI 5.0 actually
knows a "tablet" chassis type, which neither DMI nor previous ACPI
versions knew.
This also enables DMI-based and ACPI-based detection for non-x86 systems
as ACPI is apparently coming to ARM platforms soon.
I tried to minimize the vocabulary of chassis types understood and
added: desktop, laptop, server, tablet, handset. This is much less than
either APCI or DMI know. If we need more types later on we can easily
add them.
Hello list,
some socket activated service gave me the error message you can see on
the subject, maybe systemd should be more verbose in that case.
Thanks,
Dimitris
In cases where path_strv_canonicalize() returns NULL, strv_free() is
called afterwards and it will call free() on pointers which were freed
already in path_strv_canonicalize()
Found with 'cppcheck --enable=all --inconclusive --std=posix' while
working with util-linux, which has a copy of this file.

GCC manual states that "For an enum, struct or union type, you may
specify attributes either between the enum, struct or union tag and
the name of the type, or just past the closing curly brace of the
definition. The former syntax is preferred." This means that the
attribute should not be located before 'struct'. Putting it between
'struct' and the name seems cluttered. Putting it at the end seems
most readable.
This avoids clang warnings.
Clang 3.1 warned that "attribute 'packed' is ignored". This stems from
placing "__attribute__ ((packed))" at the start of structure
declarations when common practice is to place it at the end.

Mounts are "unmounted".
Swaps are "deactivated", not "turned off" nor "disabled".
Loop and DM devices are "detached", not "deleted".
Especially the deleting sounded a bit scary.
In bugreports about hangs during the late shutdown we are often missing
important information - what were we trying to unmount/detach when it hung.
Instead of printing what we successfully unmounted, print what we are
going to unmount/detach. And add messages to mark the completion of
categories (mount/swap/loop/DM).
People still don't understand what the message implies.
We have to be more verbose (or more intelligent and detect some of the
cases automatically, but that's not so easy).
