Hi,
Another thing I do when building Sage is delete the large number of
cached files that get downloaded as part of installing standard or
optional packages. This used to involve deleting spkg/optional/*.
Now what you do is:
rm -rf upstream
from SAGE_ROOT. For example, in my install that upstream directory
was "wasting" 3.4GB. Also, to delete left-over files from failed
package installs:
rm -rf local/var/tmp/sage/build/
Thanks to Andrew Ohana for clarifying this.
It would be cool if there were a make target that did all of this...,
e.g., "make cache-clean" since it is not at clear from the name that
"upstream" is a cache directory that can be safely deleted, especially
given that in the previous version of sage it (=spkg/standard/) had
much the same content, and deleting it would be devastating.
