6ad92214da boot/init: switch_root can and will kexec 
This is partly complete; we need to handle the situation where **only**
stage-0 should kexec into the next system.

This is yet to be implemented, but will be done through a configuration
that transforms the current bootloader-launched stage-1 into a stage-0,
while keeping the on-disk stage-1 stage-1.

812b02dd32 boot/init: Fix partial teardown for splash 
`#quit` would leave the `@pid` variable around, which in turn meant that
calling `#kill` after would fail since the process was already gone.

2ab969db37 boot: LUKS errors are "controlled" 
This means that we shouldn't raise an exception, but rather fail
outright. The background being black means that things *failed
successfully*, as expected.

841b835b05 boot/init: update comments in switch_root 
It better describes the reasoning for the keys than the previous
"off-the-cuff" comment I left myself.

0037614821 boot/init: Use the new evdev library 
It still uses evdev internally, but first let's change the interface,
*then* change the implementation details.

d41c454514 boot/init: Add Devices dependency type 
It's a Files dependency, but with just a bit more user friendliness when
used in an error message.

7dff001d75 boot/init: Prefer running UX tasks first 
This ensures graphical progress is shown ASAP when dependencies are
equally likely to run.

Otherwise, when the graphical step was ready, and switchroot about to
run, the shell step could run before the splash. This means that, in
practice, a long running task like e2fsck could have prevented the
splash to show. It doesn't make sense to make the other tasks depend on
a splash task!

There is no intention to implement any other special-cased ordering. If
there is the need to, it might mean that there is a deficiency in the
design.

a3c8cd78e8 boot/init: Sort tasks before running them 
This is partly to reduce the amount of loops it needs to run, but mainly
to control the order rather than rely on the order they were added in.

The control of order seems weird in a dependency-based system, but it'll
be used mainly for one thing in the next commit...

bdee7cf0e0 boot/init: Removes SingletonTask special dependency 
Instead, rely on targets.

Additionally removes the "Boot" special dependency which only made sense
when it was expected that having no dependency was an error.

a6f2195921 boot/init: Return the symlink itself for the generation 
Reading the symlink gives a relative path. That's no good in this case.

There is no actual need to resolve the symlink.

694513d9f0 boot/init: Adds missing dependency on /dev 
Though, this is only *incidental* in that for using the framebuffer the
/dev/ mount point needs to exist for /dev/fb0 to exist.

The Graphics step will succeed without that, but users of the Graphics
step might not.
