Recommended Btrfs Assistant configuration

[shuvashish76]

From Configuring BTRFS Assistant post:

I need the inotify-tools

sudo pacman -S inotify-tools

Then I’ve to do this:

@BluishHumility

Enable the grub-btrfs daemon so new snapshots are automatically added to the Grub menu.

sudo systemctl enable --now grub-btrfsd

Regenerate the Grub configuration file.

sudo grub-mkconfig -o /boot/grub/grub.cfg

Then this part is optional but I should do this:

@BluishHumility

You may wish to add GRUB_BTRFS_SNAPSHOT_KERNEL_PARAMETERS="rd.live.overlay.overlayfs=1" to /etc/default/grub-btrfs/config for booting snapshots read only. See here for more information about that: https://github.com/Antynea/grub-btrfs/blob/master/initramfs/readme.md#dracut-based-distros

Afterward, regenerate a new snapshot submenu.

sudo /etc/grub.d/41_snapshots-btrfs

Reboot and test that you are able to boot to a snapshot from Grub.

Few questions:

1. Why I don’t have @/.snapshots subvolume by default? Do I need to manually create it? | reference: according to @dalto it’s unnecessary. (old post though)
2. What are the @/var/lib/machines and @/var/lib/portables? Do I need snapshots of those as well?
3. Necessary to snapshot @cache and @log subvolumes? | reference : link
4. What are recommended “timeline snapshots” configuration from ‘Snapper Settings’? | reference : @dalto 's recommendation here.
5. Recommended “Btrfs maintenance setting” ?
6. Any manual intervention necessary for snap-pac? Do I need to enable it like grub-btrfs? It suggests no configuration is needed.
7. On plasma desktop Btrfs Assistant is in White theme as always no matter what global theme I set for the desktop. How to make it Dark?

@dalto 's preference/recommendations matters as he is one of the maintainer/dev of Btrfs Assistant
