You may be interested in checking Chris May's experience here : http://blogs.warwick.ac.uk/chrismay/entry/solaris_smf_and (and maybe contact him to give a test to your wrapper). > So I developed a launcher daemon in Python which acts as the parent > process that SMF can monitor.

When it's stable enough, maybe you'll want to merge it into mainline. If so, simply drop me a mail and we'll make a place for it in contrib/. As a side note, I see that it requires a recent version of python. Just out of curiosity, could it (more or less) easily be written in shell ? I'm asking because on the Solaris machines where I've seen haproxy, there was no python and it's very unlikely that it will be installed for a single tool. Regards, Willy
