What you cited is everywhere where you can look, I think.  I think
that "apt-config dump -c /root/.aptitude/config" would also achieve
the same results, but basically you looked into the right places.

I was asking because several reports related with "freezes" when
changing the states of the packages were due to the gzipped indices.


<note for future investigations>

I could safely try this today in another machine, and with strace it
looks like there's an endless loop looking for a apt-xapian file that
does not exist.

[pid 28407] stat("/var/lib/apt-xapian-index/index", 0x7ffc41affc40) =
-1 ENOENT (No such file or directory)
[pid 28407] stat("/var/lib/apt-xapian-index/index", 0x7ffc41b00330) =
-1 ENOENT (No such file or directory)
[pid 28407] stat("/var/lib/apt-xapian-index/index", 0x7ffc41affc40) =
-1 ENOENT (No such file or directory)
[pid 28407] stat("/var/lib/apt-xapian-index/index", 0x7ffc41b00330) =
-1 ENOENT (No such file or directory)
[pid 28407] stat("/var/lib/apt-xapian-index/index", 0x7ffc41affc40) =
-1 ENOENT (No such file or directory)


When installing "apt-xapian-index" and then running
"update-apt-xapian-index" the strace changes but it also seems to get
caught in another kind of endless loop.


Cheers.
