We had this deployed on campus last week. But you have to reinstall it after every upgrade. It is bad because: 1) you should not compile as root. There is a past bug where compiling some package would delete a system file [1] <http://trac.sagemath.org/ticket/9551>. Malicious code could hose or rootkit your system. We plan in future to have the sage tree owned by a sagemath user, which will alleviate that (only) if people remember to change to that user before customizing / adding optional packages and rebuilding. 2) bad practice since dpkg (or your distro package manager) is supposed to manage the system files, but it is technically possible. It will not work with sagemath-upstream-binary (without -full) since the SAGE_ROOT/src folder is missing and many files you need for rebuilding sage. I will try to release a 7.0.1 (rather than waiting for 7.1) which also fixes the smaller sagemath-upstream-binary in the PPAs. Note 7.0 is now in the stable PPA for 14.04.
