Here is the commit diff http://git.debian.org/?p=pkg-firebird/2.0.git;a=commit;h=db15b5744dd70864062bea0cefc15dfc74c33b66

An quick fix if you have an firebird2.0 debian/ubuntu package is to delete these lines in the /etc/init.d/firebird2.0-super

ISC_USER=sysdba
ISC_PASSWORD=masterkey
[ -r “$DBAPasswordFile” ] && . “$DBAPasswordFile”
export ISC_USER
export ISC_PASSWORD

Or get the git version of the package and copy the init script

$git-clone git://git.debian.org/git/pkg-firebird/2.0
$sudo cp 2.0/debian/firebird2.0-super.init /etc/init.d/firebird2.0-super
$/etc/init.d/firebird2.0-super restart
