# Be careful of some distro mechanism, some of them use rolling-release
# based installation instead of point-release, e.g., Arch Linux

# Rolling-release based distro doesn't have a seprate repo for each different
# build. This can cause a system call error since an app require the compatible
# version of dependencies. In other words, if you install an new app (which you
# definitely reinstall/upgrade the dependency for that app), but your other
# dependencies are old/expired, you'll end up with broken system.

# That's why we need a full system upgrade there

#---------------------SWUPD--------------------#
# 'swupd' bundles just don't make any sense. It takes about 30GB of space only
# for installing a util, e.g. 'sassc' (from 'desktop-dev' bundle, or
# 'os-utils-gui-dev' bundle, or any other 'sassc' provider bundle)

# Manual package installation is needed for that, but please don't use 'dnf'.
# The known worst impact of using 'dnf' is you install 'sassc' and then you
# remove it, and you run 'sudo dnf upgrade', and boom! Your 'sudo' and other
# system utilities have gone!

#----------------------APT---------------------#
# Some apt version doesn't update the repo list before it install some app.
# It may cause "unable to fetch..." when you're trying to install them

#--------------------PACMAN--------------------#
# 'Syu' (with a single y) may causes "could not open ... decompression failed"
# and "target not found <package>". We got to force 'pacman' to update the repos

#--------------------OTHERS--------------------#
# Sometimes, some Ubuntu distro doesn't enable automatic time. This can cause
# 'Release file for ... is not valid yet'. This may also happen on other distros
