2015-01-28linux-boot: Don't fail if /root/etc/mtab is a dangling symlink.Ludovic Courtès
Reported Joshua Grant. Patch suggested by Mark H Weaver. * gnu/build/linux-boot.scm (mount-root-file-system): Use 'false-if-exception' instead of 'when (file-exists? ...)' to account for dangling symlinks.
2015-01-05linux-boot: Make /etc/mtab a symlink to /proc/self/mounts.宋文武
Fixes <http://bugs.gnu.org/19491>. * gnu/build/linux-boot.scm (mount-root-file-system): Make /root/etc/mtab a symlink to /proc/self/mounts. * gnu/build/file-systems.scm (mount-file-system): Don't update /etc/mtab. * guix/build/syscalls.scm (mount, umount): Have #:update-mtab? default to #f.
2014-12-13activation: Copy the account skeletons when creating the 'root' account.Ludovic Courtès
* gnu/build/activation.scm (%skeleton-directory): New variable. (dot-or-dot-dot?, copy-account-skeletons): New procedure. (add-user): Use 'copy-account-skeletons'. (activate-etc): Use 'dot-or-dot-dot?'.
2014-12-09system: Don't make /boot/grub/grub.cfg a symlink to the store.Ludovic Courtès
This would not work when /boot is a separate partition, as reported by Nikita Karetnikov <nikita@karetnikov.org> in <http://bugs.gnu.org/19220>. This fixes a regression introduced in 39d1f82. * gnu/build/install.scm (install-grub): Copy GRUB.CFG instead of symlinking it, as was the case before 39d1f82. * gnu/build/vm.scm (register-grub.cfg-root): Add 'grub.cfg' parameter. Make it a permanent GC root instead of an indirect GC root. (initialize-hard-disk): Adjust accordingly. * guix/scripts/system.scm (install-grub*): Replace use of 'add-indirect-root' by the addition of a permanent GC root in %GC-ROOTS-DIRECTORY.
2014-12-06activation: Don't create unneeded "/var/guix/gcroots/etc-directory".Ludovic Courtès
* gnu/build/activation.scm (activate-etc): Don't create "/var/guix/gcroots/etc-directory".
2014-12-04system: Make /boot/grub/grub.cfg an indirect GC root.Ludovic Courtès
Fixes <http://bugs.gnu.org/19160>. * guix/scripts/system.scm (install-grub*): Make /boot/grub/grub.cfg an indirect GC root. * gnu/build/install.scm (install-grub): Make TARGET a symlink. * gnu/build/vm.scm (register-grub.cfg-root): New procedure. (initialize-hard-disk): Use it.
2014-11-28linux-modules: Correctly propagate error code from 'init_module'.Ludovic Courtès
* gnu/packages/patches/guile-linux-syscalls.patch (scm_load_linux_module): Leave 'errno' unchanged when ERR != 0. * gnu/build/linux-modules.scm (load-linux-module*): Check for the errno value of ARGS to determine whether the module was already loaded.
2014-11-28linux-boot: Load modules and their dependencies, à la 'modprobe'.Ludovic Courtès
* gnu/build/linux-boot.scm: Use (gnu build linux-modules). (load-linux-module*): Remove. (boot-system): Add #:linux-module-directory parameter. [lookup-module]: New procedure. Call 'current-module-debugging-port'. Pass #:lookup-module to 'load-linux-module*'. Map LOOKUP-MODULE on LINUX-MODULES. * gnu/system/linux-initrd.scm (base-initrd): Adjust 'boot-system' call accordingly. Adjust #:modules argument as well. * gnu/system.scm (operating-system-activation-script)[%modules]: Likewise. * gnu/system/vm.scm (expression->derivation-in-linux-vm): Likewise.
2014-11-28system: Add (gnu build linux-modules).Ludovic Courtès
* gnu/build/linux-modules.scm: New file. * gnu-system.am (GNU_SYSTEM_MODULES): Add it.
2014-11-26linux-boot: Call 'pre-mount' before 'mount-root-file-system'.Ludovic Courtès
Partly fixes <http://bugs.gnu.org/19190>. Reported by Nikita Karetnikov <nikita@karetnikov.org>. * gnu/build/linux-boot.scm (boot-system): Move PRE-MOUNT call before 'mount-root-file-system' is called.
2014-11-26linux-boot: Error out when 'pre-mount' returns #f.Ludovic Courtès
* gnu/build/linux-boot.scm (boot-system): Call 'error' when PRE-MOUNT returns #f.
2014-11-20linux-boot: Don't catch exceptions thrown by 'mount-root-file-system'.Ludovic Courtès
* gnu/build/linux-boot.scm (mount-root-file-system): Remove 'catch #t' around body. This was unneeded and even inconvenient because this procedure is called from within 'call-with-error-handling' already.
2014-11-20file-systems: Always write the options field in /etc/mtab.Ludovic Courtès
* gnu/build/file-systems.scm (mount-file-system): When OPTIONS is false, write "rw" to /etc/mtab. This fixes a bug whereby 'remove-from-mtab' in (guix syscalls) would otherwise raise a 'match-error' because of the missing field. This affected file systems mounted from the initrd, such as devtmpfs, which has options == #f.
2014-11-13vm: Set the boot flag on the root partition.Ludovic Courtès
Reported by nebuli on #guix. * gnu/build/vm.scm (initialize-partition-table): Add #:bootable? parameter and honor it. (initialize-hard-disk): Likewise.

(operating-system-activation-script): Use 'directory-union', and call 'activate-firmware'. * doc/guix.texi (operating-system Reference): Document 'firmware'.
2014-11-02system: Allow Linux-libre to find our 'modprobe' command.Ludovic Courtès
Fixes <http://bugs.gnu.org/18525>. Reported by Mark H Weaver <mhw@netris.org>. * gnu/build/activation.scm (activate-modprobe): New procedure. * gnu/system.scm (modprobe-wrapper): New procedure. (operating-system-activation-script): Use both.
2014-09-22system: Add support for boot-time mapped devices.Ludovic Courtès
* gnu/build/linux-boot.scm (boot-system): Add #:pre-mount parameter and honor it. * gnu/system/linux-initrd.scm (base-initrd): Add #:mapped-devices parameter. Add 'device-mapping-commands' variable, and use it to build the #:pre-mount argument of 'boot-system'. * gnu/system.scm (mapped-device-user, operating-system-user-mapped-devices, operating-system-boot-mapped-devices): New procedures. (device-mapping-services): Use 'operating-system-user-mapped-devices' instead of 'operating-system-mapped-devices'. (operating-system-initrd-file): Call the initrd with #:mapped-devices.
2014-09-22activation: Ensure existing user accounts have the right settings.Ludovic Courtès
* gnu/build/activation.scm (modify-user, ensure-user): New procedures. (activate-users+groups): Systematically call 'ensure-user'.
2014-09-19linux-boot: Ask fsck for a progress bar.Ludovic Courtès
* gnu/build/file-systems.scm (check-file-system): Pass '-C 0' to FSCK. Suggested by Mark H. Weaver.
2014-09-18linux-initrd: Remove now obsolete #:guile-modules-in-chroot? parameter.Ludovic Courtès
* gnu/build/linux-boot.scm (boot-system): Remove #:guile-modules-in-chroot? and related code. * gnu/system/linux-initrd.scm (base-initrd): Likewise. * gnu/system/vm.scm (expression->derivation-in-linux-vm): Remove #:guile-modules-in-chroot? argument in 'base-initrd' call.
2014-09-12activation: Honor $GUIX_NEW_SYSTEM for use by 'guix system reconfigure'.Ludovic Courtès
* gnu/build/activation.scm (activate-current-system): Honor $GUIX_NEW_SYSTEM by default. * guix/scripts/system.scm (switch-to-system): Set $GUIX_NEW_SYSTEM before loading SCRIPT.
2014-09-12activation: Set the permissions of /etc/sudoers to 440.Ludovic Courtès
* gnu/build/activation.scm (activate-etc): Move 'rm-f' to a local 'define'. When TARGET is "sudoers", make it 440.
2014-09-12activation: Make the /bin/sh symlink at activation time.Ludovic Courtès
* gnu/build/install.scm (directives): Remove "/bin/sh". * gnu/build/activation.scm (activate-/bin/sh): New procedure. * gnu/system.scm (operating-system-activation-script): Use it.
2014-09-12activation: Make sure /etc/sudoers & co. are regular files.Ludovic Courtès
Before that, 'sudo' would exit with: sudo: /etc/sudoers is not a regular file sudo: no valid sudoers sources found, quitting * gnu/build/activation.scm (activate-etc): Check if SOURCE matches 'file-is-directory?'. If not, use 'copy-file' instead of 'symlink'.
2014-09-12activation: Remove outdated comment.Ludovic Courtès
* gnu/build/activation.scm (activate-etc): Remove outdated comment.
2014-09-12activation: Factorize the link-or-copy trick.Ludovic Courtès
* gnu/build/activation.scm (link-or-copy): New procedure. (activate-setuid-programs): Use it.
2014-09-10install: Gracefully handle corner cases with 'guix system init foo /'.Ludovic Courtès
* gnu/build/install.scm (evaluate-populate-directive): Wrap body in "catch 'system-error", and report clear errors. In the symlink case, retry up EEXIST. (populate-root-file-system): Remove /var/guix/profiles/system-1-link before attempting to create it.
2014-09-08linux-initrd: Store Linux modules in a normal store directory.Ludovic Courtès
* gnu/system/linux-initrd.scm (expression->initrd): Remove #:linux and #:linux-modules parameters. Remove call to 'float-linux-module-directory'. (base-initrd): Add call to 'float-linux-module-directory'. Use it in #:linux-modules argument in the gexp. Remove #:linux and #:linux-modules arguments to 'expression->initrd'. * gnu/build/linux-initrd.scm (build-initrd): Remove #:linux-module-directory parameter. Don't create 'modules' sub-directory. * gnu/build/linux-boot.scm (boot-system): Mentin that LINUX-MODULES is a list of absolute file names.

* gnu/build/linux-initrd.scm (cache-compiled-file-name, compile-to-cache, build-initrd): New procedures. * gnu/system/linux-initrd.scm (expression->initrd)[builder]: Remove code now moved above. Use 'build-initrd'.
2014-09-08linux-initrd: Copy all the script's closure to the initrd.Ludovic Courtès
* gnu/system/linux-initrd.scm (expression->initrd): Remove calls to 'imported-modules' and 'compiled-modules'. Use 'gexp->script' with EXP. Add the result to TO-COPY. Make /init a symlink to that script, and copy its closure into the "contents" directory. Add fake /proc/self/exe symlink. * gnu/build/linux-boot.scm (load-linux-module*): Add comment about mmap. * gnu/system/vm.scm (system-qemu-image/shared-store-script): Add "-m 256". This turns out to be needed for initrds containing things like e2fsck and several modules; with the default of 128 MiB, loading libahci.ko may fail with -1.
