First of all this fixes an evaluation error I introduced in ae466ba,
which wasn't triggered by any of my own tests against the change because
there are usually no NixOS options that are declared outside of the
<nixpkgs> tree. I renamed the attribute name from "fn" to "fileName"
first and later to "fullPath" but forgot one still occuring "filename".
Thanks to @vcunat for noticing this.
Another thing that he pointed out was that the "stripPrefix" function
can be factored away entirely, because it's very similar to
"removePrefix" in <nixpkgs/lib>.
Unfortunately we can't use "removePrefix" as is, because we need to
account for the final shlash.
So instead of removing it twice and/or retaining "stripPrefix", let's
append a shlash on every "prefixesToStrip" and we can use "removePrefix"
as is.
Tested with:
taalo-build nixos/release.nix -A tests.installer.simple.x86_64-linux
And:
w3m -dump "$(
nix-build nixos/release.nix -A manual.x86_64-linux
)/share/doc/nixos/options.html"

Let's use a simple (unflipped) fold and break out the actual core
stripPrefix function from stripAnyPrefixes (I personally love
point-less^H^H^H^Hfree style but if I'd be anal I'd even go further and
factor away the "fn:").
Also, let's use path as a better name for "fn" (filename), because
that's what it is and also cannot be confused with "fn" meaning
"function".
We now toString all of the prefixes, so there shouldn't be any need to
implicily toString the extraSources anymore.

Regression introduced by e6cd147ae7.
This broke all of the installer tests, because they needed to rebuild
the manual within the test machine, while it only has a closure of the
already pre-built system in place.
The problem here was just that the order of the arguments got mixed up
in stripAnyPrefixes, so it was actually trying to strip the path off the
prefix, not the other way around.
So in the end no prefix was stripped at all, so we ended up having full
store paths in the manual, which in turn caused the build within the VM
to fail, because the prefixes differed.

The most complex problems were from dealing with switches reverted in
the meantime (gcc5, gmp6, ncurses6).
It's likely that darwin is (still) broken nontrivially.
Since 74209a4 we have initial support for the "vboxsf" (VirtualBox
shared folder) file system support. This will be cherry-picked to
release-15.09 so we need to notice people about the change.

There were quite a few configuration options which were tagged via
<literal/>, so in order to keep consistency with other docbook manuals
in the source tree, let's use <option/> here.

Commit 687caeb renamed services.virtualboxHost to programs.virtualbox,
but according to the discussion on the commit, it's probably a better to
put it into virtualisation.virtualbox instead.

For example, this allows writing
nix.package = /nix/store/786mlvhd17xvcp2r4jmmay6jj4wj6b7f-nix-1.10pre4206_896428c;
Also, document types.package in the manual.
The rationale for disabling this is: 1) systemd timers are better; 2)
it gets rid of one usually unnecessary process, which makes containers
more light-weight.
Note that cron is still enabled if services.cron.systemCronJobs is
non-empty, so this only matters if you have no declarative cron jobs
but do have user cron jobs.
Commit 159fed47bc (nixos/grub: Fix video display on efi) changed BIOS
systems to start in non-text mode as well. Enable FB_VESA to get a
framebuffer console on BIOS systems. Change FRAMEBUFFER_CONSOLE to 'y'
instead of the default 'm' to so the user doesn't need to manually load
the fbcon module anymore.
Other distros have similar defaults, at least on Arch:
CONFIG_FB_VESA=y
CONFIG_FRAMEBUFFER_CONSOLE=y
and on Ubuntu (12.04):
CONFIG_FB_VESA=m
CONFIG_FRAMEBUFFER_CONSOLE=y
Fixes#8139
By default this is now enabled, and it has to be explicitely enabled
using "enableOCR = true". If it is set to false, any usage of
getScreenText or waitForText will fail with an error suggesting to pass
enableOCR.
This should get rid of the rather large dependency on tesseract which
we don't need for most tests.
Note, that I'm using system("type -P") here to check whether tesseract
is in PATH. I know it's a bashism but we already have other bashisms
within the test scripts and we also run it with bash, so IMHO it's not a
problem here.

As promised in the previous commit, this can be used similarly to
$machine->waitForWindow, where you supply a regular expression and it's
retrying OCR until the regexp matches.

Basically, this creates a screenshot and throws tesseract at it to
recognize the characters from the screenshot. In order to produce a
result that is well enough, we're using lanczos scaling and scale the
image up to 400% of its original size.
This provides the base functionality for a new Machine method which will
be called waitForText. I originally had that idea long ago when writing
the VM tests for VirtualBox and Chromium, but thought it would be
disproportionate to the case.
The downside however is that VM tests now depend on tesseract, but given
the average runtime of our tests it really shouldn't have a too big
impact and it's only a runtime dependency after all.
Another issue is that the OCR process takes quite some time to finish,
but IMHO it's better (as in more deterministic) than to rely on sleep().

Thanks to @domenkozar for implicitly reminding me that documentation is
probably our biggest issue. And I'm a dumbass for contributing to that
situation, so let's do better than that and document it.
The current changes are only preparation for a bigger change coming real
soon[TM] in Hydra and release-tools, so right now it's still a bit
tedious to create custom channels.

‘nixos-rebuild dry-activate’ builds the new configuration and then
prints what systemd services would be stopped, restarted etc. if the
configuration were actually activated. This could be extended later to
show other activation actions (like uids being deleted).
To prevent confusion, ‘nixos-rebuild dry-run’ has been renamed to
‘nixos-rebuild dry-build’.
I think this has been accidentally dropped by a099ca4, at least there is
no reason stated, why it shouldn't be included, so I'm bringing it back.

Add a script to add git branches for each channel.
To create / update references to remote / local channels, you have to run `./maintainers/scripts/update-channel-branches.sh` while you are at the top-level of nixpkgs work directory. To make this convenient for Nixpkgs / NixOS developer, one can run the following command:
```
$ git config --add alias.fetch-channels '!sh -c "$(git rev-parse --show-cdup)maintainers/scripts/update-channel-branches.sh"'
```
Which will register the alias fetch-channels such that the script can used from sub-directory of nixpkgs by running `git fetch-channels`.
With mutableUsers = true, we now ensure that all users and groups that
were created declaratively, are updated or removed
appropriately. Thus, adding a user to users.extraUsers and then
removing it now causes the acoount to be removed from
/etc/passwd. Thus user/group management is fully congruent except that
users and groups that were created imperatively (via useradd/groupadd)
are not touched. We distinguish between declarative and imperative
users/groups by tracking the former in
/var/lib/nixos/declarative-{groups,users}.
With mutableUsers = false, you are now no longer required to specify
UIDs/GIDs for all users. The handling of mutableUsers = true/false is
the same code path; the only difference is that the "false" mode
ignores the existing contents of /etc/{passwd,group}.
The attribute ‘createUser’ is gone. It doesn't really make sense to
specify users that shouldn't be created.
