Package: btrfs-tools
Version: 4.3-1
Severity: normal
Tags: patch
Currently btrfs's boot script that runs in the initramfs always prints
messages, even if there are no btrfs filesystems present and no
errors. This should not happen when the "quiet" kernel parameter is
used. Please apply the attached patch.
Ben.

Subject: [PATCH] Show only errors from boot-time "btrfs scan" if "quiet" is
used
When the "quiet" kernel parameter is used, redirect stdout in the
initramfs boot script to /dev/null. Stop redirecting stderr, as
any errors should still be shown.
