Re: [gentoo-dev] Help testing ebuilds? golang/Fabio load balancer

[Damo Brisbane]

Cheers Michael,

I've made most those changes, including USER/GROUP*, that confuses me too;
copied pattern from another ebuild. Also removed creating separate folder
/etc/fabio.d; re this, I noticed the fabio configuration accepts either
folder path or *URL* for configuration file; not sure how this works,
though it does seem to underlie some type of arbitrariness in including
such a /etc/fabio.d folder within this ebuild.

Re for...keepdir, I found removing it then the /var/log/fabio folders were
not getting created, so keeping it in there.

http://www.calculate-linux.org/main/en/using_ebuild, says this of *keepdir*:

*Creates (if necessary) a .keep file in the given directory so that it
isn't auto-cleaned. Never create a .keep file yourself. If Portage changes
how keepdir works, then creating the file yourself will break the package.*

regards,
Damon
