Pure-FTPd RA script does not create the pid directory

[Nicola]

Actually Pure-FTPd ra script does not work out of box on ubuntu, this is for the following reasons:

- pid file in pure-ftpd wrapper is hard coded in /usr/sbin/pure-ftpd-wrapper on line 173:

push(@options, '-g', '/var/run/pure-ftpd/pure-ftpd.pid');

- the directory /var/run/pure-ftpd is deleted on each reboot
- the init script for pure-ftpd create the directory
- the ra script does not create that directory and so fails to start pure-ftpd

there are the following solutions:

1) add something like this:

if [ ! -d `dirname $OCF_RESKEY_pidfile` ];then
        mkdir `dirname $OCF_RESKEY_pidfile`
fi

at the beginning of the start function in the RA script

2) add something like this:

mkdir "/var/run/pure-ftpd", 0700 unless -d "/var/run/pure-ftpd";

after line 173 in the pure-ftpd wrapper script

3) change the wrapper script to make pid location configurable, so ra script can use a different pid file (probably require modifications to the ra script too)
4) make pure-ftpd init script lsb compliant and use it as lsb resource in pacemaker
5) make pure-ftpd init script upstart compliant and use it as upstart resource in pacemaker
