If you install a version of LATEX with a locally configured font set-up then this system is likely to produce documents that are no longer `formatting compatible'; for example, the use of different default fonts will most likely produce different line and page breaks. If you do install, on a multi-user system, a system that is configured in such a way that it is not `formatting compatible' then you should consider carefully the needs of users who need to create portable documents. A good way to provide for their needs is to make available, in addition, a standard form of LATEX without any `formatting incompatible' customisations.
