Yes, we'd tried that without success. I hadn't considered the other file attributes options though. Sadly, it seems no better. A simple test just on CentOS7 gives me this:-
Code:
# tar -cvpzf - --xattrs --acl --selinux /usr/bin/ping | (cd /tmp;tar -xzvp --xattrs --acl --selinux -f -)
tar: Removing leading `/' from member names
/usr/bin/ping
usr/bin/ping
# getcap -v /usr/bin/ping /tmp/usr/bin/ping
/usr/bin/ping = cap_net_admin,cap_net_raw+p
/tmp/usr/bin/ping
Am I doing something daft? At worst I've scanned all local files and collected the capabilities into a file that then is part of the tarball. On recovery I can apply them within my kickstart file. It's just more steps to wory about.
I have found that simply copying a file loses the capabilities, one has to cp --preserve=xattr source target Maybe I don't understand where these are stored. Maybe I don't need to know, just understand the rules I need to follow
I know I can achieve it with rsync but I can't neatly use that when doing a PXE recovery and I'd have to get the files out to all the remote locations individually too, which would be a nightmare.
I will keep digging. Any other suggestions to explore very welcome.

dtc_install_centos
dtc_install_centos(8) System Manager's Manual dtc_install_centos(8)NAME
dtc_install_centos - bootstrap a CentOS install to use in a chroot or VM
SYNOPSIS
dtc_install_centos <install root> <yum environment>
DESCRIPTION
This shell script is part of the dtc-xen package, generally to be used by the dtc panel to install a new a Xen VPS server. This script is
called by dtc_reinstall_os when the user chooses to install the CentOS operating system.
How it works: it generates a temporary yum configuration in the yum environment directory, that directs yum to act inside the install root
instead of in the base system; then it kindly requests yum to install the basesystem, centos-release and yum packages onto it. Yum then
uses the configuration to download the required (usually, security-updated) packages and then perform the RPM installation process under
the install root.
It requires both RPM and yum. It does work under Debian (it was developed in Ubuntu first). It should also work on RPM-based systems
without destroying the system-wide RPM and yum configurations.
OPTION
<install root>
Target directory where CentOS will be deployed. Must exist beforehand.
<yum environment>
Directory where yum will store the repository manifests and configuration. Will be automatically created. Cached RPMs and manifests will
be left, as usual, in a directory var/cache/yum inside the install root.
EXAMPLE
dtc_install_centos /root/yum /xen/13
This will setup the operating system in /xen/13, with the CentOS configuration folder in /root/yum.
BUGS
It's limited to CentOS 5 at the moment.
It must be run as root.
Under some circumstances, the installation process itself may kill processes running on the host machine. The chroot yum does should be
sufficient to avoid this, but we haven't been able, yet, to ascertain why this fails sometimes.
