Re: openmosix problem

Hi,

  I had actually compiled kernel from source (for adding other things on 
to the kernel), so i really dont know about any issue with rpm file.

But since you say FC5, you must be using grub.conf file found in 
/boot/grub/grub.conf

A safe option is to go and change the root= option in the kernel line

For eg:

My grub.conf looks like

#....
#    kernel .....      root=/dev/hda6
#
..
..
title OpenMosix Kernel
       root (hd0,2)
       kernel /vmlinuz-2.4.26-om-test root=/dev/hda6 ....
       initrd ....
The method that I followed is copy whatever line is there in the comment 
for root= option and paste it in my kernel's line.

If you had gone for default installation of FC5, then disk druid might 
have created logical volumes for the various partitions. I dont know 
about logical volume stuff.

For kernel Compilation I still have gcc-2.95.3 as a backup. But i think 
the compat-gcc package must do for it.

Regards,
Murali
