1f1580139e resolved.service: set DefaultDependencies=no
On systems that only use resolved for name resolution, there are usecases that
require resolved to be started before sysinit target, such that network name
resolution is available before network-online/sysinit targets. For example,
cloud-init for some datasources hooks into the boot process ahead of sysinit
target and may need network name resolution at that point already.

systemd-resolved already starts pretty early in the process, thus starting it
slightly earlier should not have negative side effects.

However, this depends on resolved ability to connect to system DBus once that
is up.

bff8f2543b units: set LockPersonality= for all our long-running services (#6819)
Let's lock things down. Also, using it is the only way how to properly
test this to the fullest extent.

Let's make use of !! to run resolved with ambient capabilities on
systems supporting them.

This reverts commit 6a716208b3.

Apparently this doesn't work.

6a716208b3 units: add SecureBits
No setuid programs are expected to be executed, so add
SecureBits=noroot noroot-locked
to unit files.

78ad7cf1b9 units: make resolved pull in its own .busname unit, but only on kdbus systems
The daemon requires the busname unit to operate, since it contains the
policy that allows it to acquire its service name.

1b8689f949 core: rename ReadOnlySystem= to ProtectSystem= and add a third value for also mounting /etc read-only
Also, rename ProtectedHome= to ProtectHome=, to simplify things a bit.

With this in place we now have two neat options ProtectSystem= and
ProtectHome= for protecting the OS itself (and optionally its
configuration), and for protecting the user's data.

417116f234 core: add new ReadOnlySystem= and ProtectedHome= settings for service units
ReadOnlySystem= uses fs namespaces to mount /usr and /boot read-only for
a service.

ProtectedHome= uses fs namespaces to mount /home and /run/user
inaccessible or read-only for a service.

This patch also enables these settings for all our long-running services.

Together they should be good building block for a minimal service
sandbox, removing the ability for services to modify the operating
system or access the user's private data.

682265d5e2 resolved: run as unpriviliged "systemd-resolve" user
This service is not yet network facing, but let's prepare nonetheless.
Currently all caps are dropped, but some may need to be kept in the
future.
