Cela comprend les démons gérés par le GNU@tie{}Shepherd (@pxref{Services Shepherd,,, guix.fr, le manuel de référence de GNU Guix}) ainsi que d'autres types d'extensions du système d'exploitation (@pxref{Composition de services,,, guix.fr, le manuel de référence de GNU Guix})."

Given this starting point, it makes sense that efforts are made to reduce the amount of time spent compiling packages, and recent changes and upgrades to the building and distribution of substitutes continues to be a topic of discussion within Guix."
 msgstr "Guix je, vo svojom jadre, distribúcia založená na zdrojových súboroch a náhradách (@pxref{Substitutes,,, guix, GNU Guix Reference Manual}).

Vzhľadom na túto skutočnosť dáva zmysel snaha o zníženie množstva času potrebného na zostavenie balíkov a nedávne zmeny v zostavovaní a šírení náhrad sú aj naďalej súčasťou rozhovorov vrámci projektu Guix."

 msgid "The perceived increase in complexity of running a Guix System container is easily justified when dealing with more complex applications that have higher or just more rigid requirements on their execution contexts---configuration files, dedicated user accounts, directories for caches or log files, etc.  In Guix System the demands of this kind of software are satisfied through the deployment of system services."
 msgstr "Pozorovanú zvýšenú zložitosť v používaní kontajnerov so systémom Guix možno jednoducho zdôvodniť keď sa musíte vysporiadať so zložitými aplikáciami, ktoré majú vyššie či len prísnejšie požiadavky na prostredie, v ktorom sú spúšťané, napr. súbory nastavení, vyhradené používateľské účty, priečinky vyrovnávacej pamäte, súbory záznamov a pod.  Systém Guix tento druh požiadaviek spĺňa nasadením systémových služieb."

 msgid "On an HPC cluster, Guix is typically used to manage scientific software.  Security-critical software such as the operating system kernel and system services such as @code{sshd} and the batch scheduler remain under control of sysadmins."
 msgstr "Vrámci vysokovýkonného zhluku počítačov sa Guix obvykle využíva na správu vedecky zameraného programového vybavenia.  Pre bezpečnosť nevyhnutné vybavenie ako je jadro operačného systému a služby ako @code{sshd} a plánovač dávkových úloh zostávajú pod dohľadom systémových správcov."

 msgid "Because Guix uniquely identifies software variants, it is easy to see if a vulnerable piece of software is in use. For instance, to check whether the glibc@ 2.25 variant without the mitigation patch against ``@uref{https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt,Stack Clash}'', one can check whether user profiles refer to it at all:"
 msgstr "Vďaka tomu, že Guix osobitne označuje rozličné verzie programov, je jednoduché zistiť, či sa používa nejaký zraniteľný program. Napríklad, pomocou nasledovného príkazu môžeme zistiť, či niektorý z používateľských profilov odkazuje na glibc@ 2.25 bez zaplátanej zraniteľnosti „@uref{https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt,Stack Clash}“:"

 msgid "Guix is based on the @uref{https://nixos.org/nix/, Nix package manager}, which was designed and implemented by Eelco Dolstra, with contributions from other people (see the @file{nix/AUTHORS} file in Guix.)  Nix pioneered functional package management, and promoted unprecedented features, such as transactional package upgrades and rollbacks, per-user profiles, and referentially transparent build processes.  Without this work, Guix would not exist."

Nix je pionierom vo funkcionálnej správe balíkov a predstavil nebývalé možnosti akými sú nedeliteľne vykonávané aktualizácie a návraty do pôvodného stavu, profily pre každého používateľa zvlášť, jasné a pochopiteľné zostavovacie postupy.  Bez tejto práce by Guix nevznikol."
