Hi Chris. Thanks fo.r the reply . The principle reason for doing/testing dual boot is to have the ability to be able to do a remote reinstall for a fresh OS on a remote box. If you know of a way to accomplish that, I'm more than willing to hear it!! Everything I've seen regarding doing reinstalling of OS, requires having access to the box, with fresh media. This is really intended to allow me to detect if the "base/master" system has been hacked, and then to immeadiately switch to the minimal OS/system, which would then invoke a netinstall for the hacked system/OS to have a clean system. So, the test is to have a dual Centos process, which is what I'm looking to implement right now. Here are the current steps I've used, feel free to tell me where I've gone off track. -Centos6.5 -Lenovo -250G Drive OS1 -insert the centos 6.5 dvd -select the fresh install -basic storage device -Fresh Installation -Create Custom Layout (-Please Select Device) LVM Volume Groups VolGroup 237972 lv_apps 10000 /apps lv_backup 10000 /backup lv_home 10000 /home lv_root 51200 / lv_swap 3824 free 127948 Hard Drive sda sda1 500 /boot ext4 sda2 237974 VolGroup physical volume (LVM) Now, at this point, I get a valid OS/grub.conf However, when I try to install the 2nd OS is when I run into issues.. So, here's what I'm trying to figure out. When I get to the (Please Select Device) page, what do I have to insert to create the minimal OS/system for the 2nd OS install. For the 2nd install, I'm looking to implement a system that has the backup/apps/home/root dirs (mt points) Do I have to have completely separate partitions for each of the OS installs? If I do, how/where do they get created? I think this is close, but again, without really knowing how to do this, one could spend hours/days on this!

And all the dracut notations are different. Oh, and grub.cfg is no longer supposed to be directly edited, you're supposed to use /etc/default/grub and grub2-mkconfig -o /boot/grub2/grub.cfg which creates grub.cfg from scratch and replaces it based on what it finds installed. > > Chris Murphy > -- > users mailing list > users@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe or change subscription options: > https://admin.fedoraproject.org/mailman/listinfo/users > Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct > Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines > Have a question?
