NextCloud in the 90's ...? I think the point is not about "add an abstraction layer" and "the problem is gone". You could make a tar.gz of a chroot in the 90's too, or you could make a snapshot of an VM. Or you could have an abstraction layer too (I did a lot for provisioning apache+mysql) like: addwebserver.sh "hostname", and addvhost.sh "customdomain" (which also included the php thing, backups, and compliant log rotation). I think the main point here was about the fact that UNIX (and internet) was more "easier to teach" because it was more simple. Or... do we need to understand and install docker, in order to teach to "list files" in the first day?
