If user/administrator is not following FHS and touching files outside
/usr/local, it's his problem. /usr/local and /etc is where administrator
can do his changes/improvements.
Sure there are *many* insane Python developers who suggest
"sudo easy_install Foo"[0] to their users, but then, when these users
come to me[1] all I'm proposing is to reinstall[2] their system (which you
should almost[3] never do on Debian).
[0] which installs eggs system wide (sic!)
[1] believe me, after tracking 10th problem that was caused by local
modifications, first thing you check next time is:
`grep \.egg bug_report_with_traceback`
[2] think twice before you will try to convince me you can uninstall
eggs
[3] last time I reinstalled my system was when I changed architecture,
and believe me - my system is one huge playground
