Bug 486378 – sys-boot/grub - grub2-reboot does not take into account the gentoo-specific grub2 path change

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Antek Grzymała (antoszka) 2013-09-28 21:31:20 UTC]

grub2-reboot does not take into account the gentoo-specific grub2 path change, so running grub2-reboot 'some-entry' results in:

############ 

When a symlink /boot/grub2 → /boot/grub is created the script works as expected. Needs patching in the installation process.

Reproducible: Always

Steps to Reproduce:
1. run grub2-reboot 'entry'
Actual Results:  
script fails upon not being able to find /boot/grub

Expected Results:  
expect script to set a single-time default grub entry for next reboot

Read your elog messages: I moved /boot/grub2 to /boot/grub with the last grub revbump (grub-2.00_p5107-r1). Sorry for the confusion, but it's better to have it there long-term.

Please re-run grub2-install and grub2-mkconfig.
