Ranked in these QuestionsQuestion Ranking
Pros
Pro Faster reboots when upgrading
Because Fedora Silverblue uses rpm-ostree, upgrades are performed by creating a new "commit" and reboots simply boot into the new commit, making the time to reboot during an upgrade faster than regular Fedora, which applies updates during the reboot.
Pro Concise "all in one" kid experience
From the pre installed apps to the interface everything about this distribution is dead simple. No necessary set up, just boot and go.
Pro Installable live cd
DouDouLinux comes as a live cd, meaning this distribution can be used on any computer not matter the OS in Live CD mode as well as installed fully onto the device depending on the hardware support.
Cons
Con Installing using rpm-ostree is more cumbersome
After updating or changing the installed packages, Silverblue requires a reboot for changes to take effect, unless the experimental apply-live command is used (rpm-ostree ex apply-live).
Con Based on an old distro
DouDou Linux is based on Debian 5, which is pretty old. So this means the software found in the distribution will be old. This also means the hardware support will be lacking compared to newer based distros. So for those that do want to install it would be a good idea to make sure the hardware is supported by Debian 5 and DouDou Linux.
