Hello, I've finally had the chance to put in a VM an instance of MicroOS Desktop with the new partition layout and. IMO, the fact that it has /var in a (nocow) subvolume is really a big improvement, so thanks Richard for that! We have /home in a subvolume too, which is also great, and it as well has the nocow flag set. I know this mostly come from a conversation we had on #microos-desktop on IRC but thinking more about that, and discussing this with some users, I wonder whether it is really the best choice. I mean, it sure is ok for /var, but for /home, using nocow means that we give up on some of the nicer BTRFS features, especially for home folders, wouldn't it? That might be especially true for MicroOS Desktop. E.g., think at being able to compress (if not the entire home directories or the entire subvolume) the user installed flatpaks (and using that as an argument "against" those that are still complaining that <Ah, but flatpaks takes a lot of space on disk!>> :-D). So, are there reasons why it's really preferable to keep the /home subvolume as nocow and I'm missing them? Or shall we switch it to cow? Also, while there, shall we evaluate adding other flags by default (i.e., things like autodefrag, or even compression itself)? E.g., AFAIUI, on Fedora, while not doing that right now, they're considering doing something like that, e.g.: https://pagure.io/fedora-btrfs/project/issue/5 Regards -- Dario Faggioli, Ph.D http://about.me/dario.faggioli Virtualization Software Engineer SUSE Labs, SUSE https://www.suse.com/ ------------------------------------------------------------------- <<This happens because _I_ choose it to happen!>> (Raistlin Majere)
