system: Make service procedures non-monadic.
* gnu/services/avahi.scm (configuration-file): Use 'plain-file' instead of 'text-file'. (avahi-service): Turn into a regular procedure that returns a <service>. * gnu/services/base.scm (root-file-system-service, file-system-service, user-unmount-service, user-processes-service, host-name-service, console-keymap-service, console-font-service, mingetty-service, nscd.conf-file, nscd-service): Likewise. (%default-syslog.conf): New variable. (syslog-service): Use it. Turn into a regular procedure. (guix-service, udev-rules-union, kvm-udev-rule, udev-service, device-mapping-service, swap-service): Likewise. * gnu/services/databases.scm (%default-postgres-hba, %default-postgres-ident): Use 'plain-file' instead of 'text-file'. (%default-postgres-config): Use 'mixed-text-file' instead of 'text-file*'. (postgresql-service): Use 'program-file' instead of 'gexp->script'. Turn into a regular procedure. * gnu/services/desktop.scm (dbus-configuration-directory): Use 'computed-file' instead of 'gexp->derivation'. (upower-configuration-file, geoclue-configuration-file, elogind-configuration-file): Use 'plain-file' instead of 'text-file'. (dbus-service, upower-service, colord-service, geoclue-service, polkit-service, elogind-service): Turn into regular procedures. (%desktop-services): Remove use of 'mlet' when iterating on %BASE-SERVICES. * gnu/services/lirc.scm (lirc-service): Turn into a regular procedure. * gnu/services/networking.scm (static-networking-service, dhcp-client-service, ntp-service, tor-service, bitlbee-service, wicd-service): Likewise. * gnu/services/ssh.scm (lsh-service): Likewise. * gnu/services/web.scm (nginx-service): Likewise. * gnu/services/xorg.scm (xorg-configuration-file): Use 'mixed-text-file' instead of 'text-file*'. (xorg-start-command, slim-service): Turn into regular procedures. (xinitrc): Use 'program-file' instead of 'gexp->script'. * gnu/system/install.scm (cow-store-service, configuration-template-service): Turn into regular procedures. * gnu/system.scm (other-file-system-services, device-mapping-services, swap-services, essential-services, operating-system-services, user-shells, operating-system-accounts): Remove now unnecessary 'mlet' and turn into regular procedures. (operating-system-etc-directory, operating-system-activation-script, operating-system-boot-script): Adjust accordingly. * doc/guix.texi (Base Services, Networking Services, X Window, Desktop Services, Database Services, Web Services, Various Services, Name Service Switch): Adjust accordingly.
