Operating Systems Linux Red Hat How to create a bootable ISO from running Linux box? Post 302692285 by Corona688 on Monday 27th of August 2012 11:09:02 AM

They're really not the same. Hard disks have partitions, ISO's do not. Hard disks are writable, ISO's are not.

It's possible certainly but there's not a direct translation -- you can't just boot an iso and get all your partitions, you have to have a special bootloader which arranges them for you, and then boots your system somehow in a manner it won't try to mount them again -- and it'd mean putting a ton of stuff into ram or unionfs so you don't get read-only-filesystem errors everywhere.

Besides, will your system even fit on ISO?

pmerge(8)						      System Manager's Manual							 pmerge(8)

NAME
pmerge - Builds a network bootable kernel. SYNOPSIS
/usr/sys/bin/pmerge bootfile kernel.name new.kernel DESCRIPTION
The kernel, vmunix, is not bootable over the network. The pmerge utility prepends the bootfile onto the kernel image (kernel.name) to cre- ate a new operating system image (new.kernel) that is bootable over the network. Instead of a booting a network loadable kernel, it is sometimes desired to bootstrap link a kernel over the network. In this case, (ker- nel.name) is the name of the sysconfigtab file on the server containing the list of modules to be loaded to the client. These modules are then linked to create a bootable kernel on the client. The pmerge utility is used by doconfig(8) to create a bootable operating system for dataless management services (DMS) client systems to boot over the network. The pmerge utility is automatically invoked by doconfig(8) during the kernel build process and should not be invoked independently. The pmerge utility is located in /var/adm/dms/dmsn.alpha/root/usr/sys/bin on the DMS server. SEE ALSO
