I'd probably be worth to do a quick individual questioning about what each formula author we have expects cwd to be, and use that instead of the unit dir.

from irc

<hazmat> a question for formula authors in the room, which directory would you want your hooks to run in.. The formula hooks directory, the formula directory, or the root of the unit directory (the formula for the unit lives at '/formula' under the unit root)?
<fwereade> what else lives in the unit root at the moment?
<fwereade> the formula directory feels natural to me but I am basically 100% ignorant
<hazmat> fwereade, with lxc, the unit root will be the fs root "/" of the container
<fwereade> ah ok
<hazmat> at the moment, there's just the service unit log file and the formula directory in the root
<fwereade> ok, the hooks directory feels wrong because... well, it's the formula's interface, and if we run in that dir we encourage people to clutter it up with other stuff
<fwereade> I don't think I have a context to judge the distinction between running in the formula dir and the unit root
<hazmat> fwereade, agreed, authors can include arbitrary library or configuration stuff in the formula, its probably nicer to address that from the root, then including a '..' everywhere or cluttering up the hooks directory
<hazmat> er... s/root/ i mean the formula directory
<fwereade> yep
* hazmat makes it so
