I noticed that this is confusing in #230, user would search for errors in
the grub-btrfs.cfg file although the old grub-btrfs.cfg file is never
overwritten with grub-btrfs.new

* Make path of "grub-mkconfig_lib" configurable
* 41_snapshots-btrfs file:
- Remove "datarootdir" variable, is no longer used
- Replace "$datarootdir/grub/grub-mkconfig_lib" with "${GRUB_BTRFS_MKCONFIG_LIB:-/usr/share/grub/grub-mkconfig_lib}"
* Config file:
- Adds new GRUB_BTRFS_MKCONFIG_LIB variable
Might be '/usr/share/grub2/grub-mkconfig_lib' on some systems (Opensuse ...)
41_snapshots-btrfs file:
* Remove "grub_script_check" variable
Config file;
* Make name of "grub-script-check" configurable
* Might be 'grub2-script-check' on some systems (Fedora ...)
#### Script:
* Snapper:
- Now, the information is retrieved from the info.xml file.
* Timeshift:
* Now, the information is retrieved from the info.json file.
* Probe informations from device:
* Add the UUID of the root and boot subvolumes
* Show full path snapshot or only name:
* Remove, this feature never worked correctly
* Grub-menu:
* Now displays the following information in separate columns:
- Date of snapshot
- Path of snapshot
- Type/Tags of snapshot if available (snapper/timeshift)
- Description/Comments of snapshot if available (snapper/timeshift)
* Possibility to display only the desired information(s) (see config file)
* Adds a header for the column title
* GRUB_BTRFS_PREFIXENTRY is remove
* Boot partition detection:
* grub-btrfs is now able to detect if the boot folder/partition is a subvolume
* GRUB_BTRFS_OVERRIDE_BOOT_PARTITION_DETECTION should no longer be needed for this case
* Variables:
* Rename some variables
* Header:
* Update the header to reflect the changes.
#### Config:
* GRUB_BTRFS_PREFIXENTRY:
* Remove, no longer use
* GRUB_BTRFS_DISPLAY_PATH_SNAPSHOT:
* Remove, no longer use
* GRUB_BTRFS_TITLE_FORMAT:
* Shows/Hides "date" "snapshot" "type" "description" in the Grub menu, custom order available.
Default: ("date" "snapshot" "type" "description")
* GRUB_BTRFS_IGNORE_SNAPPER_TYPE:
* Rename to GRUB_BTRFS_IGNORE_SNAPSHOT_TYPE
- Supports both timeshift and snapper tags/type
* GRUB_BTRFS_IGNORE_SNAPPER_DESCRIPTION:
* Rename to GRUB_BTRFS_IGNORE_SNAPSHOT_DESCRIPTION
- Supports both snapper and timeshift description/comments
* GRUB_BTRFS_OVERRIDE_BOOT_PARTITION_DETECTION:
* grub-btrfs is now able to detect if the boot folder/partition is a subvolume.
Activating this parameter should no longer be necessary for this case.
* GRUB_BTRFS_SNAPPER_CONFIG:
* Remove, no longer use
#### Readme:
* Update "What does grub-btrfs v4.xx do" section
* Adds support for timeshift
* Update "GRUB_BTRFS_DISABLE_PROTECTION_SUBMENU":
* Remove default parameter (false), not needed
* adds automatic conversion of the value to lower case
* Adds security if a false positive is detected:
* if the command "grep -qs "$gbgmp" /proc/mounts;" returns a false positive.
"rm -d" will return an error if the directory is not empty.
* 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.
* 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)
