preremove

Preremove is a term used in several technical fields to describe actions taken before the removal of an object, component, or dataset. The common thread is preparation to ensure safety, data integrity, and orderly decommissioning.

In software packaging, preremove refers to the pre-removal phase of a package lifecycle. In many package management systems, a preremove script (often named prerm) runs before the package's files are deleted. The preremove step typically stops services, releases resources, migrates or backs up relevant data, and coordinates with other components to avoid disruption. If preremove fails, the package may not be removed, or system state can be left inconsistent. Prerm is usually followed by the actual removal step and a post-removal (postrm) script for cleanup.

In information technology and asset management, preremove describes preparatory tasks performed before removing data or hardware. This can include backing up data, verifying backups, archiving, notifying affected users, revoking access, and documenting the removal plan. Compliance and safety requirements often shape preremove procedures, especially in regulated environments.

In hardware maintenance or field operations, preremove activities include powering down equipment safely, isolating circuits, securing the workspace, and tagging components for traceability. In all applications, a preremove checklist helps ensure repeatable, auditable steps.

Origin and usage: the term derives from the prefix pre- meaning before and remove. While most common in IT and packaging, preremove appears as a general descriptor for pre-removal processes across disciplines.
