Bug#331299: exim4: bashisms in init script

[Justin Pryzby]

Package: exim4
Severity: normal
Version: 4.52-1
File: /etc/init.d/exim4

The exim4 initscript /etc/init.d/exim4 uses:

#!/bin/sh

and

kill_all_exims()
{
  SIG="${1:-TERM}"
  for pid in $(pidof $NAME); do
    if [ "$(readlink /proc/$pid/root)" == "/" ]; then
      kill -$SIG $pid
    fi
  done
}

Isn't '$(' a bashism (That's what the vim maintainer said in #319825)
