this must be in f19 - in f18 I see:

/lib/i686/nosegneg/libc.so.6
/lib/i686/nosegneg/libm.so.6
/lib/i686/nosegneg/libpthread.so.0
/lib/i686/nosegneg/librt.so.1
/lib/i686/nosegneg/libthread_db.so.1
/lib/rtkaio/i686/nosegneg/librt.so.1
/lib/rtkaio/librt.so.1
/sbin/ldconfig
/usr/lib/sasl2/libanonymous.so.2
/usr/lib/sasl2/libsasldb.so.2
/usr/lib/sse2/libgmp.so.10
/usr/lib/sse2/libgmpxx.so.4
/usr/lib/sse2/libmp.so.3
/lib64/rtkaio/librt.so.1
/sbin/ldconfig
/usr/lib64/sasl2/libanonymous.so.2
/usr/lib64/sasl2/libsasldb.so.2

and it was much much worse in the past.

Actually the sqlite db doesn't just store the strings it stores a table
which has a pkg id (a number) then all the files in a specific dir for
each row.
