Bug 107181 – grub-install does not work as described when no separate /boot partition

• Status: RESOLVED FIXED
• Product: [OLD] Docs-user

[Description viraptor 2005-09-25 08:04:08 UTC]

To run grub-install user needs to create '/etc/mtab' listing partition which
holds '/boot', or '/'
If you install gentoo without '/boot' partition and '/boot' device is the same
as '/', then doing "cp /proc/mounts /etc/mtab" is wrong.
It lists double '/' mounts - one from cd image and one from chroot. If you just
copy '/proc/mounts' and have '/boot' dir on '/' mount, then you have to remove
first '/' mount, or grub-install will find cd image first and complain about not
finding kernel file or '/boot'.

Reproducible: Always
Steps to Reproduce:
1. install gentoo with only / partition
2. "cp /proc/mounts /etc/mtab"
3. /etc/mtab lists 2 '/' partitions - first of which is from image on cd and
that one if found by grub-install

Can someone please verify this?

grub-install fails

This is what happens. Removing the first line with rootfs makes it work.

Now I have to reinstall with a /boot partition and make sure whatever I do does
not break :)

grub-install works

excluding the rootfs line works in both cases, as expected :)

Fixed. Thanks for reporting.
