Ahh, you are indeed right -- the old conffile is still present and marked as 
obsolete by dpkg. (I guess I must have missed that amongst the new directory 

So, yes... local admin changes are preserved; the admin is just left with a 
mess because of the wrong path to the .so. Feel free to assign whatever 
priority you would like to give this in the BTS, but it does look like it is 
in the "needs fixing for wheezy" (with minimal changes) category. As one of our 
release managers commented when we were discussing this bug earlier:

[18:03] <adsb> arguably http://release.debian.org/wheezy/rc_policy.txt 5a says 
"package must not be on crack", but I think that's about as explicit as we 
get. "must not screw the admin over" shouldn't need to be codified

That does not appear to be correct with php5-xcache 2.0.0-2 currently in 

$ grep zend_extension /etc/php5/mods-available/xcache.ini
zend_extension = /usr/lib/php5/20100525+lfs/xcache.so

... so this problem is a problem that will keep on giving.

/etc/php5/mods-available/xcache.ini is also a conffile again (whereas many of 
the other php module packages seem to have gone to ucf for the configuration 
file handling to help cope with these sorts of situations).
