In this chapter, we will perform a few additional tasks to prepare for constructing the toolchain and the chroot environment. A directory in
$GLAD will be created for the installation of the toolchain, add an unprivileged user
glaucus to reduce risk. An appropriate build environment for that user will be created as well.
The unit of time used to measure how long glaucus cerata take to prepare, configure, build and install is referred to as “CCU” (Ceras Construct Unit) for toolchain and chroot cerata, and "CEU" (Ceras Envenomate Unit) for final system cerata. Both units will be provided in the future (they will probably be implemeted to be automatically measured).
