There are a few ideas what it might look like to do by default in Fedora. https://bugzilla.redhat.com/show_bug.cgi?id=1851276 Transparent compression has been in Btrfs since early days. Zlib was supported when it was first merged into the kernel around 12 years ago. LZO followed soon after. Zstd is new, but it's supported since kernel 4.14, which isn't definitely not new in Fedora terms. But yeah, you'll be able to turn it off. Whether by mount option or by attribute. It may also be reasonable to opt in or out by kickstart. One option not discussed so far is: do the work to enable it in the installer, and only enable it by default via a GNOME Boxes express installation (injecting a kickstart into the installation). I'm not sure if that's more trouble than it's worth, but it could make for significantly smaller Fedora VMs that are also decently likely to be a bit faster due to (a) typically slower write performance inside of VMs anyway (b) fewer reads and writes results in a net gain in performance due to the compression. -- Chris Murphy _______________________________________________ test mailing list -- test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to test-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@xxxxxxxxxxxxxxxxxxxxxxx
