> Where does this go?
Wherever the check for, e.g. sage-flags.txt is done, i.e. at startup. The
idea is to make sure that those two features are available, because they
are actually required by Sage, and if they are missing the error messages
tend to be very confusing (see the description for a taste).
Note that this actually happens at least when one does a quick chroot and
doesn't mount either /dev/pts and /dev/shm.
Just to record the relative importance of the two: pseudottys are
absolutely required for sage (pexpect), while shared memory seems to be
only used through pyprocessing, i.e. maybe only dsage needs it.
