Bug#88413: [PATCH]: modconf broken with ash

[David Whedon <dwhedon@gordian.com>]

Package: modconf
Version: 0.2.31
Severity: grave

ash is used in boot-floppies.  This bug is marked grave because is breaks
boot-floppies.  modconf works fine with bash.

$ /bin/ash < modconf
Syntax error: Bad substitution
$

Now I'll use ash directly and it will give a better error message:
$ diff -u modconf.orig modconf

$ ./modconf
./modconf: 115: Syntax error: Bad substitution
$ 


Here is a patch that fixes it.  My guess is that even though the BASH_VERSION
is not defined ash still needs to parse the offending line 115. It fails.
