 ### 🔎 Description:
-Improves grub by adding "btrfs snapshots" to the grub menu.
+grub-btrfs improves the grub bootloader by adding a btrfs snapshots sub-menu, allowing the user to boot into snapshots.

-You can boot your system on a "snapshot" from the grub menu.  
-Supports manual snapshots, snapper, timeshift ...
+grub-btrfs supports manual snapshots as well as snapper, timeshift, and yabsnap created snapshots.

-##### Warning: booting on read-only snapshots can be tricky
+##### Warning: booting read-only snapshots can be tricky

-If you choose to do it, `/var/log` or even `/var` must be on a separate subvolume.  
-Otherwise, make sure your snapshots are writable.

 ### ✨ What features does grub-btrfs have?
-* Automatically list snapshots existing on root partition (btrfs).
-* Automatically detect if `/boot` is in separate partition.
-* Automatically detect kernel, initramfs and Intel/AMD microcode in `/boot` directory on snapshots.
-* Automatically create corresponding "menuentry" in `grub.cfg`
-* Automatically detect the type/tags and descriptions/comments of Snapper/Timeshift snapshots.

-### 📚 Usage
-After installation the grub main menu needs to be generated to make a menuentry for the snapshots sub menu. Depending on the Linux distribution the commands for that are different:
+### 📚 Manual usage of grub-btrfs
+To manually generate grub snapshot entries you can run `sudo /etc/grub.d/41_snapshots-btrfs` which updates `grub-btrfs.cfg`. You then need to regenerate the GRUB configuration by running one of the following commands:
+
 * On **Arch Linux** or **Gentoo** use `grub-mkconfig -o /boot/grub/grub.cfg`.  
 * On **Fedora** use `grub2-mkconfig -o /boot/grub2/grub.cfg`

+This process can be automated to occur whenever you create or delete snapshots but this process is slightly different depending upon your distributions choice on init system. See the relevant instructions for your init system below.

 #### Warning:
 Some file locations and command names differ from distribution to distribution. Initially the configuration is set up to work with Arch and Gentoo (and many other distributions) out of the box, which are using the `grub-mkconfig` command. 
-However, Fedora for example uses a different command, `grub2-mkconfig`.
-Edit `GRUB_BTRFS_MKCONFIG` variable in `/etc/default/grub-btrfs/config` file to reflect this. (e.g. `GRUB_BTRFS_MKCONFIG=/sbin/grub2-mkconfig` for Fedora)

-On most distributions and installs, the grub installation resides in `/boot/grub`. If grub is installed in a different place, change the variable `GRUB_BTRFS_MKCONFIG` in the config file accordingly. For Fedora this is `GRUB_BTRFS_GRUB_DIRNAME="/boot/grub2"`. Also the command to check the grub scripts is different on some system, for Fedora it is `GRUB_BTRFS_SCRIPT_CHECK=grub2-script-check`

 #### Customization of the grub-btrfsd daemon

-Grub-btrfs comes with a daemon script that automatically updates the grub menu when it sees a snapshot being created or deleted in a directory it is given via command line.
+Grub-btrfs comes with a daemon script that automatically updates the grub menu when it sees a snapshot being created or deleted in a directory it is given via command line. You must install `inotify-tools` before you can use grub-btrfsd.

 The daemon can be configured by passing different command line arguments to it. 
-The arguments are:
-* `SNAPSHOTS_DIR`
-This argument specifies the path where grub-btrfsd looks for newly created snapshots and snapshot deletions. It is usually defined by the program used to make snapshots.
-E.g. for Snapper this would be `/.snapshots`
+The available arguments are:
+* `SNAPSHOTS_DIRS`
+This argument specifies the (space separated) paths where grub-btrfsd looks for newly created snapshots and snapshot deletions. It is usually defined by the program used to make snapshots.
+E.g. for Snapper or Yabsnap this would be `/.snapshots`. It is possible to define more than one directory here, all directories will inherit the same settings (recursive etc.).
+This argument is not necessary to provide if `--timeshift-auto` is set. 
 * `-c / --no-color`
 Disable colors in output.
 * `-l / --log-file`
 This arguments specifies a file where grub-btrfsd should write log messages.
+* `-r / --recursive`
+Watch the snapshots directory recursively
 * `-s / --syslog`
+* `-o / --timeshift-old`
+Look for snapshots in `/run/timeshift/backup/timeshift-btrfs` instead of `/run/timeshift/$PID/backup/timeshift-btrfs.` This is to be used for Timeshift versions <22.06. You must also use `--timeshift-auto` if using this option.
 * `-t / --timeshift-auto`
-This is a flag to activate the auto detection of the path where Timeshift stores snapshots. Newer versions (>=22.06) of Timeshift mount their snapshots to `/run/timeshift/$PID/backup/timeshift-btrfs`. Where `$PID` is the process ID of the currently running Timeshift session. The PID is changing every time Timeshift is opened. grub-btrfsd can automatically take care of the detection of the correct PID and directory if this flag is set. In this case the argument `SNAPSHOTS_DIR` has no effect.

+### 🪀 Automatically update grub upon snapshot creation or deletion
+Grub-btrfsd is a daemon that watches the snapshot directory for you and updates the grub menu automatically every time a snapshot is created or deleted.
+By default this daemon watches the directory `/.snapshots` for changes (creation or deletion of snapshots) and triggers the grub menu creation and re-installation of grub if any changes are noticed.
+Therefore, if Snapper or Yabsnap is used with its default directory, the daemon can just be started and nothing needs to be configured. See the instructions below to configure grub-btrfsd for use with Timeshift or when using an alternative snapshots directory with Snapper/Yabsnap.

+### Development
+Grub-btrfs uses a rudimentary system of automatic versioning to tell apart different commits. This is helpful when users report problems and it is not immediately clear what version they are using. 
+We therefore have the following script in `.git/hooks/pre-commit`:
+
+``` bash
+#!/bin/sh
+
+echo "Doing pre commit hook with version bump"
+version="$(git describe --tags --abbrev=0)-$(git rev-parse --abbrev-ref HEAD)-$(date -u -Iseconds)"
+echo "New version is ${version}"
+sed -i "s/GRUB_BTRFS_VERSION=.*/GRUB_BTRFS_VERSION=${version}/" config
+git add config
+```
+
+This automatically sets the version in the `config`-file to `[lasttag]-[branch-name]-[current-date-in-UTC]`.
+In order to create a Tag we don't want to have this long version. In this case we set the version manually in `config` and commit with `git commit --no-verify`. This avoids running the hook. 
+

 * DESCRIPTION
 Grub-btrfsd is a shell script which is meant to be run as a daemon.
 Grub-btrfsd watches a directory where btrfs-snapshots are created or deleted via inotifywait and runs grub-mkconfig (if grub-mkconfig never ran before since grub-btrfs was installed) or ~/etc/grub.d/41_snapshots-btrfs~ (when grub-mkconfig ran before with grub-btrfs installed) when something in that directory changes.

Dorian Stoll	ece8d87151	Add support for GRUB patches from SUSE Some GRUBs out there (Fedora, openSUSE) have an option that makes all paths relative to the default subvolume of the filesystem. This can be used to include /boot in your snapshots and roll them back without having to regenerate grub.cfg. However, enabling that option will break grub-btrfs, because loading the kernel from a different snapshot requires the paths to be absolute. To make this work, GRUB has to be told explicitly to access the root subvolume when booting to a snapshot.	2024-03-10 12:56:37 +01:00
