Improvement:

  • Script:

    • Add filter to ignore snapper's snapshot "type or description" during run "grub-mkconfig" (#158) ...
    • Add possibility to boot without init(rd,ramfs) (#164) :
      • For a snapshot to be valid, it must contain a boot folder and a kernel from the official list
        (or have been added to the custom kernel list)
      • if a snapshot doesn't contain an init(rd,ramfs), it will be detected as valid.
      • Suppress script stop when an init is not found
    • Adds trap command on EXIT signal:
      • Now umount command will launch on EXIT signal.
      • Adds a function called by the trap on EXIT signal to unmount and delete the temporary folder.
        (That should be the end of multiple tmp.xxxxxxxxxx in /tmp)
        • If the command fails, retry every 2 seconds. After 10 attempts, it will stop and display a warning.
        • If the command is successful, "Succes" will be displayed.
      • Adds "grub-btrfs" as a prefix to the temporarie mount folder.
        (before = tmp.xxxxxxxxx , now = grub-btrfs.xxxxxxxxxx)
    • Rework the creation of the "grub-btrfs.cfg" file:
      • Before, the "grub-btrfs.cfg" file was deleted and then the new configuration was written.
        No backup was made.
      • Now, the new configuration will be written in a temporary file "grub-btrfs.new" and then analysed with the "grub_script_check" command before being finally written in the "grub-btrfs.cfg" file.
        If an error is detected, the "grub-btrfs.new" file will coexist with the old "grub-btrfs.cfg" file, if it exists.
  • Config file:

    • Add Two new variables:
      • "GRUB_BTRFS_IGNORE_SNAPPER_TYPE"
        Ignore specific type of snapper's snapshot during run "grub-mkconfig".
        Type = single, pre or post.

      • "GRUB_BTRFS_IGNORE_SNAPPER_DESCRIPTION"
        Ignore specific description of snapper's snapshot during run "grub-mkconfig".
        See Config file

Miscellaneous:

  • Script:

    • Removes double negation in file test operators
    • Remove redundant check
    • Deactivate the script as soon as possible …
      With these changes, the script will be disabled as soon as possible, if :
      • "GRUB_BTRFS_DISABLE" If this variable is set to "true"
      • "btrfs-progs isn't installed" This package is required to retrieve information from the btrfs filesystem.
      • "grub-mkconfig_lib couldn't be found" This library is required because the script depends on it.
      • "Root filesystem isn't btrfs" grub-btrfs currently checks only the btrfs snapshots present on the root partition.
    • Corrects printf format string
    • Update header installation section:
    • Deletes unused code:
      • Limit generation of menuentries if exceeds 250 has never been used.
        Uses "GRUB_BTRFS_LIMIT" (default 50) instead.
    • Write-protect user data
      • The script does not need write access to the data.
        Adds "ro" flags to provide protection against accidental writing.
  • Readme:

    • Update "Installation section":
      • Adds required dependencies
      • Indicates that the command "update-grub", is an alias to "grub-mkconfig" on Debian-like distributions.
