Isnt it?
Well, it depends on what your application needs to run properly. Likely you
can make do with just libc/ld-linux and everything that is listed in 'ldd
<yourapp>' output, plus obviously the files that come with the app itself
(perhaps some data files or so?)
This is far from a whole unstable - you don't need much in /etc (perhaps the
passwd file, perhaps resolv.conf, don't forgent the linker config files
ld.so.*), you don't have any daemons, you don't need most/all of /var, even
if it's an X app, you only need the client libraries, no X server etc. (just
make sure you connect to the X server via TCP and not via domain socket, or
make X somehow create an additional socket inside your chroot).
Oh, and another thing you'll need probably is one of the libnss_* files (most
likely libnss_files), if your application does any lookups on the user
database (/etc/passwd).
I'd start by just copying libc and the linked libraries into the chroot, and
then expanding this until the app stops breaking.
A totally different approach would be to use debootstrap to actually install a
complete unstable chroot. It may be easier, but it's a bit a waste of
diskspace.
Dunno, perhaps some go-between is possible, to have just a dpkg database, but
no base system installed. Sometimes things will break if you don't have all
the Essential: yes packages installed, but you'll probably figure out what is
missing.
