About "elgatolinux" review:
@gato2707 said it's no alternative to Calligra in repos. @dago has reply quickly saying Libreoffice is available in the repos.
Also, he doesn't like the PKGBUILD, wants a easier way to install external apps. It could be two posibilities, a comunity repo or something like .deb in Debian. Download and install.
Finally, he said that Illumos will be the future kernel of KaOS. Is it true? First notice for me.
