idmapper

README

idmapper

idmapper is a package which will map a process to the highest usera id available.

Unlike the newuidmap and newgidmap commands found in Shadow, idmapper does not require this user to exist and will not check /etc/subuid for valid subuid ranges.

[!NOTE]

This repository should be imported as code.cloudfoundry.org/idmapper.
