Option to install HoloIso on a partition instead of erasing the entire drive needed

[boredpengu]

Problem:
Many users will have the same problem I am facing: For initial testing of HoloIso one does not want to erase the entire drive, but instead install the system on a separate partition alongside an existing installation - for testing stability of the existing hardware.

Suggested solution:
Either 1) add the option to select a partition instead of a full drive in HoloIso Installer

Or 2) provide a quick guide on howto edit the /usr/bin/holoiso_installer script for enabling installation on a partition instead of the full drive

Thanks in advance!

I did this by manually executing the commands in the installation script.

	parted ${DEVICE} mkpart primary fat32 2M 256M
	parted ${DEVICE} mkpart primary btrfs 256M 15G
    parted ${DEVICE} mkpart primary ext4 15G 16G
    parted ${DEVICE} mkpart primary ext4 16G 100%
	root_partition="${INSTALLDEVICE}2"
    var_partition="${INSTALLDEVICE}3"
    home_partition="${INSTALLDEVICE}4"
	mkfs -t vfat ${INSTALLDEVICE}1
	fatlabel ${INSTALLDEVICE}1 holo_efi
	mkfs -t btrfs -f ${root_partition}
	btrfs filesystem label ${root_partition} holo_root
    mkfs.ext4 -F ${var_partition}
    e2label ${var_partition} holo_var
    mkfs.ext4 -F ${home_partition}
    e2label ${home_partition} holo_home

If you have experience with parted or cfdisk, perform the above partitioning operations manually and assign the corresponding label.

Then replace the content in ${} and execute the subsequent code.

    sync && udevadm trigger
    holoiso_bootstrap --username "${HOLOUSER}" --password "${HOLOPASS}" --root_password "${ROOTPASS}"

He decided to show the result but he didn't show how to reach it.
May you explain me more?
Also, which version did he use in the video?
