You should probably use debconf to ask, though. I wouldn't be surprised
to find that some Emdebian users want a stable host and an unstable
target.
If you still want to find the default suite, you should be able to do it
by parsing apt-cache policy output, though I'm not sure how stable that
format is. Here's some Perl code that worked for me:
my ($cur_pri, $max_pri, $max_pri_suite);
open POLICY, "apt-cache policy |" or die "open: $!";
for (<POLICY>) {
if (/^\s*(\d+)/) {
$cur_pri = $1;
} elsif (defined($cur_pri)
&& (!defined($max_pri) || $cur_pri > $max_pri)
&& /^\s+release o=Debian,a=(\w+),l=Debian,c=main\s*$/) {
$max_pri = $cur_pri;
$max_pri_suite = $1;
}
}
close POLICY;
if (defined($max_pri_suite)) {
print "Default suite is $max_pri_suite\n";
} else {
print "No sources for Debian main\n";
}
