Allowing variables in stanzas

[Removed by request]

I'm using Ubuntu 11.10 dev and upstart 0.9.7-3. I wanted to use a variable in chdir because it is used on some other places in the script too. For example the part looked so:

env DIRECTORY=/srv/test
chdir $DIRECTORY

But this wasn't allowed and the script failed. Maybe upstart could get the ability to use variables in stanzas so that we haven't to write the string more than one time.

While directory specification might not be that important to me, setting max open files should allow reading system value.

For example if I set max open files in init script as:

MAXFILES=$(( `cat /proc/sys/fs/file-max` / 2 ))
ulimit -n $MAXFILES

upstart version could allow something like:

limit nofile `$(( `cat /proc/sys/fs/file-max` / 2 ))`

or variable that has been initialized before in env.
