Bug#856929: initramfs-tools: Please add option to clear screen at the beginning
Package: initramfs-tools
Version: 0.127
Severity: normal
Tags: patch
Hi,
When using the initramfs for kdump, the screen might already contain
text. Without clearing the screen, the output of the initramfs will
overwrite the screen only partially with old text staying on the screen.
Thus please add a kernel option 'clear' to clear the screen at the
beginning (patch for 0.127 attached).
