haproxy -f /etc/haproxy.cfg -sf $(cat $PIDFILE) would do it

>haproxy -h
HA-Proxy version 1.4.18 2011/09/16
Copyright 2000-2011 Willy Tarreau <w#1wt.eu>

Usage : haproxy [-f <cfgfile>]* [ -vdVD ] [ -n <maxconn> ] [ -N <maxpconn> ]

        [ -p <pidfile> ] [ -m <max megs> ]


        -v displays version ; -vv shows known build options.

        -d enters debug mode ; -db only disables background mode.

        -V enters verbose mode (disables quiet mode)

        -D goes daemon

        -q quiet mode : don't display messages

        -c check mode : only check config files and exit

        -n sets the maximum total # of connections (40000)

        -m limits the usable amount of memory (in MB)

        -N sets the default, per-proxy maximum # of connections (40000)

        -p writes pids of all children to this file

        -de disables epoll() usage even when available

        -ds disables speculative epoll() usage even when available

        -dp disables poll() usage even when available

        -dS disables splice usage (broken on old kernels)

        -sf/-st [pid ]* finishes/terminates old pids. Must be last

arguments.
