Public bug reported:
Binary package hint: plymouth
In maverick plymouth 0.8.2-2ubuntu5.
I'll skip the amount of grief plymouth has cost me in multiple places,
it has been echoed by enough other people in bugs and blogs (long story
short, I never upgraded to lucid because of plymouth). I eventually went
to maverick and it's a tiny bit better, but as far as encryption and
initrd goes, it of course grabs the console away and stops script that
read input from working.
My encryption script did a simple
read PASSWORD
feed password to cryptsetup
read never works because of plymouth.
I edited /usr/share/initramfs-tools/scripts/init-top/plymouth
and commented out
#printf '\033[?25l' > /dev/tty7
#/sbin/plymouthd --mode=boot --attach-to-session
--pid-file=/dev/.initramfs/plymouth.pid
#/bin/plymouth show-splash
I have no idea why this is there, what purpose it serves, but now that I
removed them, I can read the encryption password from the command line
again and boot properly.
Please consider removing this if it's not absolutely necessary, and more
generally when you design system enhancements, remember those who
actually need boot messages and console access to work reliably and
couldn't care less about splash screens and eye candy that removes
access to the system when it boots.
Thanks.
