* gnu: system: Add fusermount3 to setuid-programs.Maxim Cournoyer2022-07-14
| | | | | | | | | Fixes <https://issues.guix.gnu.org/47716>. * gnu/system.scm (%setuid-programs): Add /bin/fusermount3 from the fuse-3 package. Reported-by: raingloom <raingloom@riseup.net>
* system: <operating-system> compiler truly honors the 'system' argument.Ludovic Courtès2022-06-15
| | | | | | | | | | Fixes <https://issues.guix.gnu.org/55951>. * gnu/system.scm (operating-system-compiler): Parameterize '%current-system' and '%current-target-system' before calling 'operating-system-derivation'. * tests/system.scm ("lower-object, %current-system sensitivity"): New test.
* system: Fix typo, add doc.Maxim Cournoyer2022-06-06
| | | | | * gnu/system.scm (operating-system-kernel-arguments): Fix typo in doc. (boot-parameters->menu-entry): Add doc.
* system: Improve warning when using LUKS mapped devices without UUIDs.Maxim Cournoyer2022-05-21
| | | | | | | | | | | | This corrects two problems with the previous mapped devices warning: 1. It wasn't clear how to correct the situation. 2. The output would be repeated multiple times, as many times as the procedure is called during a system reconfigure. * gnu/system.scm (operating-system-bootloader-crypto-devices): Memoize procedure. Include the mapped devices source location information in the warnings. Add a hint to help users fix the warning.
* services: shepherd: Default to version 0.9.Ludovic Courtès2022-04-07
| | | | | | | | | * gnu/services/shepherd.scm (scm->go): Define 'shepherd&co' and pass it to 'with-extensions'. (shepherd-configuration-file): Call 'start-in-the-background' when it is defined. (<shepherd-configuration>)[shepherd]: Default to SHEPHERD-0.9. * gnu/system.scm (hurd-default-essential-services): Use SHEPHERD-0.8.
* system: Use 'shadow-with-man-pages' in %BASE-PACKAGES-UTILS.Ludovic Courtès2022-03-21
| | | | | * gnu/system.scm (%base-packages-utils): Replace SHADOW with SHADOW-WITH-MAN-PAGES.
* system: Improve 'read-boot-parameters' incompatibility diagnostic.Ludovic Courtès2022-03-16
| | | | | | | | | | | | | Previously, when reading an incompatible "parameters" file, 'guix system' would print a warning and then crash with a wrong-type-arg backtrace because code expects 'read-boot-parameters' to always return a <boot-parameters> record. * gnu/system.scm (read-boot-parameters): Upon incompatibility, raise an error instead of returning #f. Also raise a '&fix-hint' condition. * tests/boot-parameters.scm ("read, construction, mandatory fields"): Define 'test-read-boot-parameters' as a macro; expect 'formatted-message?' exceptions rather than #f returns.

| | | | | | | | | | | | | | | | | | | | | | This is to make it less surprising, given the common convention sets forth by the kernel Linux command-line parameters. * gnu/build/linux-boot.scm (boot-system): Rename '--load', '--repl', '--root' and '--system' to 'gnu.load', 'gnu.repl', 'root' and 'gnu.system', respectively.
