> Well, what's the purpose of canonicalizing SAGE_ROOT in the `sage`
script?
It's precisely for the reason I said: we need to be able to determine a
usable value of `$SAGE_ROOT` before we can do ''anything'' with Sage.
It's true that it doesn't matter that it's canonical, but we still need to
dereference symbolic links in `$0` (the script filename) to find
`$SAGE_ROOT`. Since #5852, we support an installation where somebody
makes a symbolic link from `/usr/local/bin/sage` to
`/usr/local/sage/sage-4.8/sage` or whatever.
I agree the code duplication is not so nice, but I still think the patch
can be reviewed as-is.
