File System Recommendation

[Malix-Labs]

1. @Malix-off in the discord server :

   I have seen in
   https://vanillaos.org/blog/article/2024-07-22/interview-with-luca-di-maio-and-mirko-brombin-exploring-immutability-in-vanilla-os-2-orchid#how-does-the-atomicity-approach-in-vanilla-os-compare-to-other-operating-systems
   that it's fs independant, but are there some in which it works better (e.g. due to compression or thin-provisioning better interaction) ?

2. Tau in the discord server :

   ABRoot is filesystem independant.
   Vanilla itself only supports the LVM btrfs structure that the installer formats.
   ABRoot does work better with Copy-on-Write Filesystems tho like btrfs.

   For the var partition it doesn't really matter. I would still recommend btrfs but you can use pretty much anything.

It is suggested to allocate at least 50 GB of storage for Vanilla OS. The minimum suggested partitioning structure is:

• GPT/MBR partitioning table (in Device selection)
• 1 GB (1024 MB) storage for Boot partition in ext4 format.
• 512 MB storage for EFI (System) partition in fat32 format.
• 20.5 GB (20992 MB) storage for the Root partition pool unformatted.
• Optionally, create a Swap partition for hibernation support (we use zram by default). The remaining storage should be used for the var partition in btrfs format. This partition is where all of your data is stored.

• ...
• LVM Thin Provisioning: Efficient disk space usage with logical volumes, allowing virtual filesystems larger than the available physical storage and supporting the dynamic allocation of space as needed for the two roots.
• ...
• Vanilla Installer: ... support for encrypting the /var partition with LUKS2. Supports manual partitioning and network configuration during installation.
