This commit adds a Guix System service to handle allocation of subuid and subgid requests. Users that don't care can just add themselves as a subid-range and don't need to specify anything but their user name. Users that care about specific ranges, such as possibly LXD, can specify a start and a count. * doc/guix.texi (Miscellaneous Services): Document it. * gnu/build/activation.scm (activate-subuids+subgids): New variable. * gnu/local.mk: Add gnu/tests/shadow.scm. * gnu/system/accounts.scm (sexp->subid-range): New variable. * gnu/system/shadow.scm (%root-subid): New variable; (subids-configuration): new record; (subid-range->gexp): new variable; (assert-valid-subids): new variable; (delete-duplicate-ranges): new variable; (subids-activation): new variable; (subids-extension): new record; (append-subid-ranges): new variable; (subids-extension-merge): new variable; (subids-service-type): new variable. * gnu/tests/shadow.scm (subids): New system test.
