Public bug reported:
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-bfe5-447d-be50-36d100934630
linux /boot/vmlinuz-2.6.32-10-generic-pae root=/dev/sda9
initrd /boot/initrd.img-2.6.32-10-generic-pae
}
I expected the options "quiet splash" to be included, like this:
linux /boot/vmlinuz-2.6.32-10-generic-pae root=/dev/sda9 quiet splash
In addition, a "recovery mode" entry was not automatically generated.
The os-prober package may be responsible for this bug, I am not sure.
