Re: Bug#108640: grub: doesn't load symlinks kernel images on reiserfs (big drive)

[Jochen Hoenicke]

Hello,

I thought I had fixed symlinks for new reiserfs.  I haven't tested
symlinks to files, though, or maybe the format has changed again.

Do directory symlinks work for you? I.e if you make a symlink to
/boot, can grub follow it correctly?  You can try this in the grub
shell under linux it should make no difference.

You can generate more debugging information by enabling REISERDEBUG.
For this open fsys_reiserfs.c and change in line 25 the #undef to a
#define.  The easiest way to capture this output is to start 
"grub --no-curses" in an xterm.  You can redirect the output to a file
but then you have to type blindly.

Did you have reiserfs before?

I don't think that this is the case but the debugging information
would tell this.
