How can I do the following to 100 servers. If you can help script the following lines

1. Backup first the original /etc/grub.conf
2. Modify the system kernel paramter "crashkernel" . This is done by editing the /etc/grub.conf file and add "crashkernel=256M@32M " to the kernel line.

3. Make an entry in the /etc/kdump.conf
    net my.server.com:/kdump/
4. Enable kdump service
   chkconfig kdump on

To enable reversion, you should introduce some form of revision control. RCS is perfectly adequate if the configs are different on every system. If they are the same and you only want to make the change once, you could use Subversion, CVS or git. Are you familiar with any of these?

Sorry can't help you with actual config changes - but if you know what they are and you post them then I could maybe help with scripting
