Bug#1051279: grub2 2.12~rc1-7 does no honor GRUB_CMDLINE_LINUX_DEFAULT="quiet" -- no quiet in kernel argument

[M. Zhou]

Source: grub2
Version: 2.12~rc1-7
Severity: important

Dear Maintainer,

After the recent upgrade, some users experienced the unbootable
issue #1051271 . I fixed the issue, and booted with 2.12~rc1-7,
but I figured out that the newly generated grub config does not
honor the GRUB_CMDLINE_LINUX_DEFAULT="quiet" in the new
/etc/default/grub.ucf-dist file.

As a result, the "quiet" kernel argument is missing from the 
generated grub.cfg in /boot/grub.

For users who rely on this variable for customized kernel
hbehavior, this might cause more issues. Hence I'm marking
this issue as important.
