Bug#500112: grub-pc: grub is failing to start at boot (go to rescue mode immediately) when using jfs.mod (prefix issue)

[Benoit Hamet]

Package: grub-pc
Version: 1.96+20080724-10
Severity: normal

Hi all,

This was already discussed and solved upstream some time ago. In short :
when using grub-pc with the jfs file system, grub fails when starting and fallback in the rescue mode. This is due to a bug (AFAIK) in the jfs way of treating trailing /
A possible workaround is to remove the ending / in the grub-install script, when building the command line of grub-mkpackage --prefix=...'

IIRC the experimental package solve this problem (20080831).

Regards,

Benoit.
