provant debian 10!: swap/file



Acabo de provar la debian-buster-DI-rc1-amd64-DVD-1 i, amb el
particionat manual, si no estableixes una partició de memòria virtual,
el DebianInstaller encara et deixa anar l'absurd discurs de la
conveniència d'això i pregunta si estàs realment segur(a) de voler
continuar sense això.

En un ordinador amb 32GiB de memòria RAM l'absurd s'eleva al quadrat.
