installed 22.1-0ubuntu4~feisty1, should i remove /etc/emacs21/site-start.d

[imputerate]

 per system > admin > synaptic pkg
manager:
i replaced emacs 21 with emacs 22 [-gtk is the essential
pkg]

the remove/install went well, i think; one item demanded that
i opt for "complete" removal [incl. config files]; so i did;
the final lines of the log were:

Setting up emacs22-common (22.1-0ubuntu4~feisty1) ...
Setting up emacs22-bin-common (22.1-0ubuntu4~feisty1) ...
Setting up emacs22-gtk (22.1-0ubuntu4~feisty1) ...
Byte-compiling add-on packages, please wait... done.
Setting up emacs (22.1-0ubuntu4~feisty1) ...

ALSO:

 i assume emacsen-common 1.4.17 stayed as it was;

BUT:

 there were these warning lines earlier on in the log:

 dpkg - warning: while removing emacs21-common, directory
`/etc/emacs21/site-start.d' not empty so not removed.

 dpkg - warning: while removing emacs21-common, directory `/etc/
emacs21' not empty so not \ removed.
-----------------------------------


here's what's in /etc now;

/etc/emacs21/site-start.d# ls
20gnus-init.el
/etc/emacs22/site-start.d# ls
00debian-vars.elc

i haven't rebooted since the "upgrade";

can i rely on emacs22 to:

go to /etc/emacs22 and find 00debian-vars.elc,

instead of:

going to /etc/emacs21 and running 20gnus-init.el?

or should i expunge everything in /etc/emacs21?

thanks, imputerate
