Sure, after all it's in the FAQ (Q5.2) and documented under help(Startup).  

I also use it at work on different system where 

	a) I may or may not have write permissions (Linux), or 

	b) want to keep my package directory outside of the versioned R
	   directory tree (Windoze).

So thumbs up from me.  And under Debian, thanks to the useful expansion of
R_LIBS from pre-defined values, you get your own as well as the systems
directory in /usr/lib and /usr/local/lib.  

The only other thing to consider would be a multi-user setting. You could
experiement with Renviron.site if you want to leave the conffile
/etc/R/Renviron alone.  I have not tried this.
