The structure of the grp stack is designed to accommodate these changes efficiently. It consists of several elements the Real GID (RGID), the Effective GID (EGID), and one or more Saved GIDs (SGIDs). The RGID represents the group that the process was spawned from, while the EGID is used for most permission checks. SGIDs come into play when a process needs to drop certain privileges temporarily but may need to reclaim them later.

This can lead to a decrease in the structural integrity of the pipeline and reduce its overall lifespan. Proper installation and maintenance procedures can help prevent delamination and ensure the long-term performance of FRP pipelines.
