Fair point... BUT, does this perhaps present an opportunity?... during initial install, a power failure will probably not result in a bootable system anyway, and so perhaps there are performance gains to be had (even if smaller) with other filesystems by having a "no fsync" mode of dpkg for initial installation. Not that this specific issue with btrfs isn't important, I'm just wondering if we can learn somthing from why this particular load is slow... and perhaps make some other things faster in the process. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/601299 Title: btrfs slow install -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
