Public bug reported:
Binary package hint: initramfs-tools
First symptom : at boot, the message "No init found. Try passing init= bootarg."
Boot fails.
I'm upgrading to Natty from Maverick
My configuration :
/dev/sda1 : /boot
/dev/sda5 : an encrypted luks volume containing an LVM physical volume
the volume groupe name is "arwen", the logical volume name for / is "racine"
the device containing rootfs is named /dev/mapper/arwen-racine
hence, my grub menuentry looks like this :
menuentry 'Ubuntu, avec Linux 2.6.38-8-generic' --class ubuntu --class
gnu-linux --class gnu --class os {
recordfail
savedefault
set gfxpayload=$linux_gfx_mode
insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set=root
uuiduuid-uuid-uuid-uuid-uuiduuiduuid
linux /vmlinuz-2.6.38-8-generic root=/dev/mapper/arwen-racine ro
quiet splash vt.handoff=7
initrd /initrd.img-2.6.38-8-generic
}
Sometimes, the error is more verbose, I've get yersterday a message which said
the system attempt to mount /dev/mapper/arwen on initramfs' /root, but it's a
mistake, my rootfs is on /dev/mapper/arwen-racine.
The root= kernel argument is correct, but an initramfs script mades a mistake.
>From initramfs' shell I've mounted my /boot partition, then create a new
>initrd.img hardcoding /dev/mapper/arwen-racine path on the line 91 of
>scripts/local, then reboot, then choose my new initramfs from the grub editor…
The boot does'nt complain and I'm writing this bug report from Natty. :)
So, there is a bug in one script into initramfs which troncate the volume group
name of / .
I've not found where.
