From 58f430f69e71f95cedab9912c1c9f2cc8660fad9 Mon Sep 17 00:00:00 2001 From: Giacomo Leidi Date: Tue, 8 Oct 2024 00:40:26 +0200 Subject: accounts: Add /etc/subuid and /etc/subgid support. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit adds a new record type, and serializers and deserializers for it in (gnu build accounts). Each instance of this record represents one line in either /etc/subuid or /etc/subgid. Since Shadow uses the same representation for both files, it should be ok if we do it as well. This commit adds also , a user facing representation of . It is supposed to be usable directly in OS configurations. * gnu/build/accounts.scm (subid-entry): New record; (write-subgid): add serializer for subgids; (write-subuid): add serializer for subuids; (read-subgid): add serializer for subgids; (read-subuid): add serializer for subuids. * gnu/system/accounts.scm (subid-range): New record. * test/accounts.scm: Test them.
