Bug Description
Binary package hint: grub2
Running sudo update-grub on Ubuntu Karmic detects the installation of Ubuntu Lucid (alpha release) and adds it to grub.cfg, but it does not include the "quiet splash" options as needed for Pylmouth to work. Without it, Plymouth gives this error: "mountall problem--can't mount plymouth", although Lucid does eventually reach Xsplash.
Here's how I came across this bug. I installed Ubuntu Lucid (alpha release) to my hard disk from live USB. I remembered to untick "Install boot loader", as I wanted to continue to use the existing GRUB2 on my system, on /dev/sda5. Ubuntu Karmic Koala was already installed on an encrypted LVM on /dev/sda6.
When I restarted the system, Ubuntu Lucid was not included in GRUB2's list of kernels, as expected. I booted Karmic and ran sudo update-grub to include it in grub.cfg. It included Lucid, but it did not include the quiet and splash options for it. These options are needed for Lucid to boot with Plymouth enabled.
Here's the relevant entry from grub.cfg, after running sudo update-grub:
menuentry "Ubuntu lucid (development branch) (10.04) (on /dev/sda9)" {
insmod ext2
set root=(hd0,9)
search --no-floppy --fs-uuid --set c8bc0939-
linux /boot/vmlinuz-
initrd /boot/initrd.
}
I expected the options "quiet splash" to be included, like this:
linux /boot/vmlinuz-
In addition, a "recovery mode" entry was not automatically generated.
The os-prober package may be responsible for this bug, I am not sure.

I had some problems with the "splash" option #491045. LINUX_DEFAULT.
So I removed "splash" from GRUB_CMDLINE_
After that I noticed that an regular update removed "quiet splash" from GRUB_CMDLINE_ LINUX_DEFAULT.
I just could not find the specific update.
Maybe that helps.
