This shell script is for partitioning of LVM Installations. The Ubuntu Installer didn't allow self-partitioning of LVM Installations. But i want to split some things like the home directory for easier changes afterwards.
| Amount of Space | Purpose |
|---|---|
| 30 GB | / (root) |
| 10 GB | /programs (For flatpak and snap) |
| 1 GB | swap |
| other free space | /home |
If you already have created LVM partitions e.g. from Ubuntu 20.04, then you can skip until 4. In the Ubuntu Live Environment:
- create 3 Partitions without a file system
- 1GB Big (efi Partition)
- 2 MB BIOS Grub Partition (not needed if you only use EFI)
- The last one should be the free space which is left.
- Edit script 22.04-live-1.sh and insert the variable partition. Put in the location of the in 1.2 created partition. (biggest one)
- execute 22.04-live-1.sh (This will create 4 LV root, home, programs, swap)
- Start Installation
- choose root as Mount Point /
- choose programs as Mount Point /programs
- choose swap as swap
- choose home as Mount Point /home
- After Installation execute 22.04-live-1.sh (This will change that flatpak and snap make use of the programs partition)
( If you use a USB-Stick with Ventoy, you can Inject the script file in the Ubuntu Live Enviroment -> https://www.ventoy.net/en/doc_live_injection.html )
The partition-vX.tar.gz file is ready for use with ventoy. (The File will appear in /home [Thats because every distribution has it's own username]) Just create on the ISO Partition a directory ventoy and create a File named ventoy.json with a content like this
{
"injection": [
{
"image": "/nameofyouriso.iso",
"archive": "/partition-vX.tar.gz"
}
]
}
replace nameofyouriso with the name of your iso file and partition-vX with your actual version! Copy your iso and the partition-vX.tar.gz to the iso Partition.
