# Without the function of OS re-installation templates in control panel which provided by cloud companies(many companies even have not).
# A independent VPS with only one hard drive is lack of the secondary hard drive to format and copy new OS file to main hard drive.
# So PXE installation need to use memory as a 'hard drive' temporary.
# For redhat series, the main OS installation file is 'squashfs.img', for example, this is the link of rockylinux 8 LiveOS iso file:
# http://dl.rockylinux.org/pub/rocky/8/Live/x86_64/Rocky-8-MATE-x86_64-latest.iso
# If you download and mount it, you will found that the size of '/LiveOS/squashfs.img' is 1.55GB!
# It means in first step of netboot installation, this 1.55GB file will be all downloaded and loaded in memory!
# So and consider other install programs if necessary, even 2GB memory is not enough, 2.5GB only just pass, it's so ridiculous!
# Debian 11 PXE installation will be able in low memory mode just 512M, why redhat loves swallow memory so much, is shame on you!
# Redhat 9 slightly improved the huge occupy of the memory, 2GB RAM machine can run it successfully.
# Technology companies usually add useless functions and redundant code in new version of software increasingly.
# They never optimize or improve it, just tell users they need to pay more to expand their hardware performance and adjust to the endless demand of them. it's not a correct decision.

# Ubuntu 22.04 and future versions started to using "Cloud-init" to replace legacy "d-i(Debian installer)" which is designed to support network installation of Debian like system.
# "Cloud-init" make a high hardware requirements of the server, one requirement must be demanded is CPU virtualization support.
# Many vps which are virtualizated by a physical machine, despite parent machine support virtualization, but sub-servers don't support.
# Because Ubuntu 22.04 and future version removed critical file of "initrd.gz" and "linux" which are critical files to implement "d-i".
# For example, the official of Ubuntu 22.04(jammy) mirror site doesn't provide any related files to download, the following is here:
# http://archive.ubuntu.com/ubuntu/dists/jammy/main/installer-amd64/current/legacy-images/
# So we have no possibility to accomplish Ubuntu network installation in future.
# Canonical.inc is son of a bitch, they change back and forth, pood and pee everywhere.
