(which will be a bash script) before the main Python script. Or, since
`sage-env` ideally should just set up environment variables and do nothing
else (right?), we could turn it into a config file that was read
independently by `sage-sh` and by `sage`. This would also allow us to rely
less on environment variables for random things seemingly unrelated to the
shell.

of sage is moved) that this should be updated?
It should store the current startup environment. It would change if the
root directory of Sage is moved, for example, yes. But if a user decided
to change an environment variable in a Sage session with `os.environ` that
wouldn't become reflected in the file, of course.

python
Oh, right, of course. So then yes, `sage` should be bootstrapped in the
way you described [comment:43 above].
