From 1da99396dc65993ba34ac0370ca5d6acda6a3322 Mon Sep 17 00:00:00 2001 From: Mark H Weaver Date: Sun, 18 Mar 2018 07:02:37 -0400 Subject: [PATCH] Add support for gdbm-1.14. As of gdbm-1.14, 'gdbm_errno' no longer exists as a binary interface. It has been replaced by 'gdbm_errno_location', a function that returns int*. We now use this new interface if it's available. --- gdbm.scm | 18 ++++++++++++++++-- 1 file changed, 16 insertions(+), 2 deletions(-) diff --git a/gdbm.scm b/gdbm.scm index b92992f..4d38cc3 100644 --- a/gdbm.scm +++ b/gdbm.scm @@ -17,6 +17,9 @@ ;; You should have received a copy of the GNU General Public License ;; along with this program.

2020-05-20bootloader: grub: Allow booting from a Btrfs subvolume....* gnu/bootloader/grub.scm (strip-mount-point): Remove procedure. (normalize-file): Add procedure. (grub-configuration-file): New BTRFS-SUBVOLUME-FILE-NAME parameter. When defined, prepend its value to the kernel and initrd file names, using the NORMALIZE-FILE procedure. Adjust the call to EYE-CANDY to pass the BTRFS-SUBVOLUME-FILE-NAME argument. Normalize the KEYMAP file as well. (eye-candy): Add a BTRFS-SUBVOLUME-FILE-NAME parameter, and use it, along with the NORMALIZE-FILE procedure, to normalize the FONT-FILE and IMAGE nested variables. Adjust doc. * gnu/bootloader/depthcharge.scm (depthcharge-configuration-file): Adapt. * gnu/bootloader/extlinux.scm (extlinux-configuration-file): Likewise. * gnu/system/file-systems.scm (btrfs-subvolume?) (btrfs-store-subvolume-file-name): New procedures. * gnu/system.scm (operating-system-bootcfg): Specify the Btrfs subvolume file name the store resides on to the `operating-system-bootcfg' procedure, using the new BTRFS-SUBVOLUME-FILE-NAME argument. * doc/guix.texi (File Systems): Add a Btrfs subsection to document the use of subvolumes. * gnu/tests/install.scm (%btrfs-root-on-subvolume-os) (%btrfs-root-on-subvolume-os-source) (%btrfs-root-on-subvolume-installation-script) (%test-btrfs-root-on-subvolume-os): New variables.
