Il demone gestore e gli strumenti Shepherd sono scritti nel linguaggio Guile (una delle implementazioni del linguaggio Scheme), che viene utilizzato anche per definire le impostazioni e i parametri di avvio dei servizi. Shepherd \u00e8 gi\u00e0 utilizzato nella distribuzione GuixSD GNU\/Linux ed \u00e8 previsto anche per l'uso in GNU\/Hurd, ma pu\u00f2 funzionare su qualsiasi sistema operativo compatibile con POSIX per cui \u00e8 disponibile il linguaggio Guile.      <\/p>\n<p>Shepherd si occupa dell'avvio e dell'arresto dei servizi, tenendo conto delle interconnessioni tra i servizi, determinando dinamicamente e avviando i servizi da cui dipende il servizio selezionato. Shepherd supporta anche la definizione di conflitti tra servizi e previene la loro esecuzione simultanea. Il progetto pu\u00f2 essere utilizzato sia come sistema di init principale (init con PID 1), sia in modo isolato per gestire i processi in background di singoli utenti (ad esempio, per avviare tor, privoxy, mcron, ecc.) con esecuzione con i diritti di tali utenti.     <\/p>\n<p>Novit\u00e0 principali:  <\/p>\n<ul>\n<li class=\"l\"> \u00c8 stata realizzata la concetto dei servizi temporanei (transient), scollegati automaticamente dopo il completamento a causa della cessazione del processo o della chiamata del metodo &#171;stop&#187;, che pu\u00f2 essere necessaria per i servizi sintetizzati che non possono essere riavviati dopo la conclusione del lavoro.\n<li class=\"l\"> Per la creazione di servizi simili a inetd, \u00e8 stata aggiunta la procedura &#171;make-inetd-constructor&#187;.\n<li class=\"l\"> Per la creazione di servizi attivati dall'attivit\u00e0 di rete (in stile attivazione socket systemd), \u00e8 stata aggiunta la procedura &#171;make-systemd-constructor&#187;.\n<li class=\"l\"> \u00c8 stata aggiunta una procedura per avviare il servizio in background &#8212; &#171;start-in-the-background&#187;.\n<li class=\"l\"> Nella procedura &#171;make-forkexec-constructor&#187; sono stati aggiunti i parametri &#171;:supplementary-groups&#187;, &#171;#:create-session&#187; e &#171;#:resource-limits&#187;.\n<li class=\"l\"> \u00c8 garantito il funzionamento senza blocco durante l'attesa dei file PID.\n<li class=\"l\"> Per i servizi senza il parametro &#171;#:log-file&#187; \u00e8 assicurata l'uscita su syslog, mentre per i servizi con il parametro &#171;#:log-file&#187; &#8212; la registrazione dei log in un file separato con l'indicazione del tempo delle registrazioni. I log dal processo non privilegiato shepherd vengono salvati nella directory $XDG_DATA_DIR.\n<li class=\"l\"> \u00c8 stata interrotta la supporto per la compilazione con Guile 2.0.
