Messages from initscripts are written on top of those from previous kernel.
If You are having a good day adding "clear" hook would be nice ;)

Sure, this is free since busybox doesn't properly use an ncurses library and just hopes that terminals respond to the ANSI escape sequence it writes out. I'll include this in the next release.

A new hook would be the best because fix could be implemented in just one place, and it could be easily disabled in case of emergency with "disablehooks=clear" in kernel command line ;)

And that glitch affects at least all users of binary drivers with kexec.

No, the problem you're describing is specific to uvesafb. I use a kernel mode vesa FB with the nvidia blob driver and have never run into this problem.

I've added the clear command as part of mkinitcpio-busybox in testing (1.20.1).
