Can you delete unnecessary syscalls from SEOS package to free space?

Products

• CA Privileged Access Manager - Server Control (PAMSC)

Issue/Introduction

When you download and install the PAMSC package (pkg), it downloads SEOS_syscall files, which are not required for the technology we're installing on. This causes it to take up more space on the system memory than necessary. Is it possible to prevent this behavior when installing this package?

Environment

PAMSC 14.1

Cause

By default all kernels modules are inside the package

Resolution

customize_eac_rpm -q  rpm_file    can be used to build a smaller rpm package that will contain only kernel modules for the platform in question, e.g., an rpm for a range of RHEL OS versions when customization is done on a RHEL system.   

This type of customization allows one to have an installation that continues to work even if the Linux kernel or OS is upgraded later.   

Internally, this customization operation uses the sekmodutil script.   See sekmodutil -h screen for all possibilities.   

Using the Sekmodutil Tool

If it is desired to free up even more disk space after installation and operation after upgrading OS to a new major version (e.g., RHEL 7.9  -> RHEL 8.2) is not a concern, one can run sekmodutil  -x, which will leave only kernel modules for a particular OS major release, e.g., RHEL 7.x
