Hello. My question briefly: I want to get a compact base system, but can
not do this by of the dependencies.
Now for more details: during reconfigure installed a package A. A depend of
B, B depend of C,
C depend of D, .. and all of them I don't need.
Removing package А will probably require a lot of work, but I can change
the dependencies of the package
and rebuild A at next reconfigure. But how to specify it in
system_configuration.scm?
Such variant:
(define-public PKG-A
(package (inherit PKG-A))
(name ...
(version ...
(arguments
#:tests? #f
#:configure-flags LIST-OF-CHANGED-CONFIGURE-OPTIONS
...
- probably is wrong? Then maybe so:
(define B
(package (inherit PKG-A))
...
(define-public B)
In my case, the unfortunate chain of dependencies is:
mariadb <- qtbase <- qtsvg <- python-pyqt <- hplip <- sane-backends <-
colord
and colord supports "--disable-sane" flag.

Hello!
The 'colord' service allows you to pass a custom package to be used
instead of the default. So you can do something along these lines:
[-- Attachment #1.2: config.scm --]
[-- Type: text/plain, Size: 498 bytes --]
(define-module (local packages)
#:use-module (guix packages)
#:use-module (gnu packages gnome))
(define-public colord-minimal
(package
(inherit colord)
(name "colord-minimal")
(inputs '()) ;look ma, no dependencies!
(arguments
`(#:configure-flags '("--disable-sane")))))
(use-modules (gnu)
(local packages))
(operating-system
[...]
(services (cons (colord-service
#:colord colord-minimal)
%base-services)))

Note: I haven't tested this, but hopefully it should give an idea :-)

Perfect!
You reminded about services and there is an idea even easier: just remove
colord-service.
How? This issue has already been discussed in *"Deleting services from
%desktop-services in operating system declaration"*
thread.
How much I understand, it will give the same effect?
I just do not work with physical documents, and so I absolutely don't need
either scanning or printing. And I would be glad
to completely get rid of Samba, CUPS and Sane in my system =)

I was able to remove colord only like this:
(remove (lambda (service)
(eq? (service-value service) colord)) ;; colord-service-type not
exported
%desktop-services)
and after removing, the login to Xfce freezes for some time. In short,
something goes wrong =)
Where to see logs?
