23 I'm not sure how to interpret this: please forgive my stupidity. I'll try to
24 guess:
25
26 - In case you meant: are there mountpoints such as "/var/usr/something" which
27 would then point to another partition: no.
28
29 - In case you meant: do you use a line like "kernel (hd0,0)/boot/bzImage" in
30 your grub.conf, which then points to a real kernel-file
31 like /boot/kernel-2.6.11-hardened-r13: yes, but the problems are also arising
32 when I link directly to /boot/kernel-2.6.11-hardened-r13 in grub.conf.
33
34 Moreover, both these kind of configurations are the same on the working
35 system.
36
37 Did I understand you correctly, or do I fail to understand your mail?
38
39 Regards,
