(linux-libre-5.9-version, deblob-scripts-5.9, linux-libre-5.9-pristine-source, linux-libre-5.9-source, linux-libre-headers-5.9, linux-libre-5.9): New variables. (linux-libre-version, linux-libre-pristine-source, linux-libre-source, linux-libre): Point to linux-libre-5.9*. (linux-libre-with-bpf): Use linux-libre-5.9. Leo Famulari 2020-10-24build: Add GUIX_GIT_KEYRING variable for make authenticate....* Makefile.am (GUIX_GIT_KEYRING): New variable. (authenticate): Use GUIX_GIT_KEYRING to select the keyring branch reference. * doc/contributing.texi (Building from Git): Add an example about the use of GUIX_GIT_KEYRING. Miguel Ángel Arruga Vivas 2020-10-18system: Add locale to boot-parameters....* gnu/system.scm (define-module)[export]: Add boot-parameters-locale. (<boot-parameters>)[locale]: New field. [boot-parameters-locale]: New accessor. (read-boot-parameters): Read locale field. (operating-system-boot-parameters): Provide operating-system locale to boot-parameters record. (opeating-system-boot-parameters-file): Likewise. * Makefile.am (SCM_TESTS): Add tests/boot-parameters.scm. * tests/boot-parameters.scm: New test file. Miguel Ángel Arruga Vivas 2020-10-05build: Use a 'guile' executable that doesn't warn about locales....This gets rid of: guile: warning: failed to install locale when running the 'guix' command on a foreign distro where 'GUIX_LOCPATH' isn't set. * Makefile.am (pkglibexec_PROGRAMS, guile_SOURCES, guile_LDADD) (guile_CFLAGS): New variables. (install-exec-hook): New target. (AUX_FILES): Remove 'guile-launcher.c'. * configure.ac: Use 'GUILE_FLAGS'. Ludovic Courtès 2020-10-05self: Use a 'guile' that doesn't complain about locales....Since commit ba48895899a117d6ace2209c3f54411a4a989133, selected UTF-8 locales are bundled. However, because 'guix-command' is itself a Guile script, users would still see Guile's warning, particularly on foreign distros: $ LC_ALL=sdf guix foo guile: warning: failed to install locale hint: Consider installing the `glibc-utf8-locales' [...] User commands would print that warning, but more importantly, each invocation of 'guix substitute' would print it, even though 'guix-daemon.service' explicitly chooses "en_US.utf8", which is in 'glibc-utf8-locales'. This leads to confusion since users would keep seeing this message unless/until they realize they also need to install 'glibc-utf8-locales' in root's profile. This patch gets rid of "guile: warning: ..." for a guix-pulled 'guix' command. * guix/self.scm (specification->package): Add "gcc-toolchain". (quiet-guile): New procedure. (guix-command): Use it. * gnu/packages/aux-files/guile-launcher.c: New file. * Makefile.am (AUX_FILES): Add it. Ludovic Courtès 2020-10-04cuirass: Distribute hurd-manifest.scm....This is a follow-up to commit fdbf8a7a75e9d63957ea6d8a63181aa131edeaea. * Makefile.am (EXTRA_DIST): Oops, add build-aux/cuirass/hurd-manifest.scm. Jan (janneke) Nieuwenhuizen 2020-09-30scripts: system: Add support for image-type....* guix/scripts/system.scm (list-image-types): New procedure, (%options): add "image-type" and "list-image-types" options, remove "file-system-type" option, (show-help): adapt accordingly, (%default-options): also adapt, and set the default "image-type" to "raw", (perform-action): add image-type argument and remove file-system-type argument, (process-action): adapt perform-action call, (system-derivation-for-action): remove base-image argument, add image-type argument, and use it to create the image passed to "system-image". * tests/guix-system.sh: Adapt accordingly and add a test for "--list-image-types" command. * doc/guix.texi (Building the Installation Image, Invoking guix system): Adapt accordingly.
