Description Jon Marston 2004-03-20 11:44:58 UTC

Current grub versions in portage don't support the UFS2 file system used by default in the latest versions of the FreeBSD install.
This makes dual booting with Gentoo/FreeBSD using grub impossible.
Grub gives an error of "File system unknown"

Reproducible: Always
Steps to Reproduce:
1.Install Gentoo
2.Install FreeBSD
3.Set up grub to dual boot gentoo and freebsd

Actual Results:  
Boot on FreeBSD fails with a grub error of "filesystem unknown"

Expected Results:  
Grub should have recognised the UFS2 file system used by FreeBSD

it didn't work for you? what happened?

Comment 2 Jon Marston 2004-03-21 11:24:10 UTC

I copied the ebuild and patch texts to the relevant files, as described by the thread. But the emerge process always dies at the point of patching with a .out file repetitively printing output as follows:

Why not simply chainload FreeBSD?

Comment 4 Robert Moss (RETIRED) gentoo-dev

UFS2 support is in grub-0.95. Watch this space...

Comment 5 Robert Moss (RETIRED) gentoo-dev

This is implemented in grub-0.95, for which an ebuild is provided in bug #55732. Adding this bug as a dependency.

Full UFS2 support is apparently provided in grub-0.95-20040823, although I am unable to test this. Closing - please reopen if this isn't the case.
