system: Make accounts and groups at activation time.
* gnu/services/base.scm (guix-build-accounts): Remove #:gid parameter; add #:group. Remove 'password' and 'gid' fields in 'user-account' form, and add 'group'. (guix-service): Remove #:build-user-gid parameter. Remove 'id' field in 'user-group' form. * gnu/system.scm (etc-directory): Remove #:groups and #:accounts. No longer produce files "passwd", "shadow", and "group". Adjust caller accordingly. (%root-account): New variable. (operating-system-accounts): Add 'users' variable. Add %ROOT-ACCOUNT only of 'operating-system-users' doesn't already contain a root account. (user-group->gexp, user-account->gexp): New procedures. (operating-system-boot-script): Add calls to 'setenv' and 'activate-users+groups' in gexp. * gnu/system/linux.scm (base-pam-services): Add PAM services for "user{add,del,mode}" and "group{add,del,mod}". * gnu/system/shadow.scm (<user-account>)[gid]: Rename to... [group]: ... this. [supplementary-groups]: New field. [uid, password]: Default to #f. (<user-group>)[id]: Default to #f. (group-file, passwd-file): Remove. * gnu/system/vm.scm (operating-system-default-contents)[user-directories]: Remove.
