We've looked at pylint but not at oelint-adv.

Ideally, we imagined our recipes as three-liners (inherit dpkg, SRC_URI, SRCREV
or similar) which wouldn't require much of style. In the (very distant) future,
we'd need automatically created recipes or even not need recipes at all (all
necessary metadata is already inside the Debian-style source packages). This
not being the case today :) , I think oelint-adv could be evaluated whether
it's useful and configurable enough for Isar. Experiences welcome.

Regarding your specific questions -- sysconfdir, etc, bin and friends -- those
vars are very OE-specific and in are in case of Isar all managed by the Debian
package building infrastructure. So my wish would be exactly about it -- if the
tool turns to be useful for Isar, we shouldn't force people to deal with many
false positives.

Other than that, seems that the tool is not intended to provide pure formatting
guidance, but also real style guidance -- in that case, I think major effort
would be needed to make it useful to check for Isar development patterns.

With kind regards,
Baurzhan
