Installed using subiquity focal iso, and btrfs filesystem for the whole drive.
Enabled compression via force-compress=lzo mount option in fstab. Rerun btrfs defrag tool to recurrsievely compress /boot with lzo. Upgraded to new grub, and dpkg-reconfigure it just in case. Rebooted. in grub console, check package version grub> echo $package_version 2.04-1ubuntu26.8 Completed boot just fine. Thus I think grub2 in focal with btrfs lzo compression still boots fine. ** Tags removed: verification-needed-focal ** Tags added: verification-done-focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1911440 Title: Build using distro minilzo To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1911440/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
