āāZipping it up into a cache image: use --numeric-owner option for tar
This document focuses on HostGIS Linux (a Slackware derivative) but aside from the specifics about installation settings, it should be 99% applicable to Slackware as well.
Technically, you could probably do this on a hardware PC without VMWareVMware, but VMWare VMware does make it more convenient.
Start by creating a new VM in VMWareVMware.
* The disk and RAM stats can be minimal, as the system will never see live use.
* There is no need to create the entire disk at once during the setup.
* Do set the timezone properly. The internal clock does not use UTC/GMT.

* Hostname: template * Domain: internal.lan* IP config: as appropriate for your LAN
* Nameserver: no
Reboot into your new HGL install, and log in.

== Zipping it up into a cache image ==
A VE CT cache is just a tar.gz file of the entire filesystem, excluding some very dynamic stuff which gets populated by the OS at runtime anyway:
