How Does The Script Works ?

1. Volumes mounted on subdirectory of /tmp:

• Subvolume of root volume on /
• FAT volume in /fat

2. Root FileSystem of selected distro is extracted on top of it.

3. Mentioned packages are installed.

4. Grub is installed.

How Rootfs of Distribution is created ?

• By the means of web-scraping one of the following is used:
  • Download latest rootfs tarball of the distribution from there mirrors
  • Download latest packages to create a working package manager for the distribution, using the same to create rootfs
    • eg. https://codeberg.org/zz/strap

How it takes care of different File Systems | Organizations ?

• Backtracking
• Backtracking selected Devices is possible with:

lsblk -s

Multi Boot

it's recommended to install os-prober to add boot entries for OS and Distros not installed from this script.

grub.cfg in the FAT partition is responsible:

• it holds entries to grub configs of all distributions.
• The entry 'OTHER' in grub menu will take you to the entries in this file.

Why I switched from EFI-Stub to GRUB ?

• FDE
• Legacy Bios
• VMs as OVMF entries are not persistent
• Smaller FAT partition as kernel & initrd doesn't reside on Fat partition.
