I am setting up a RHEL 6 diskless installation. It is working via PXE over nfs. However, I am concerned about patching. How do I patch the diskless image if it is just a collection of files representative of a RHEL 6 installation?
For instance, if I want to upgrade to the latest FireFox, how do I patch my diskless “image”?
How do I update the root filesystem “image” using RPMs?
yum tool can update packages from an alternate installation root.
For instance, if your root directory is at
/srv/nfs/rhel6root then you can update the image with:
yum --installroot=/srv/nfs/rhel6root update
rpm tool has a similar option.
rpm --root=/srv/nfs/rhel6root -q firefox
