[gentoo-dev] Defining S= from ebuild phase, src_unpack() ?

[Samuli Suominen]

Quoting PMS, Chapter 8:

"All ebuild-defined variables discussed in this chapter must be defined
independently of any system, profile or tree dependent data, and must
not vary depending upon the ebuild phase."

This is very inconvinent rule for example, github tarballs where the
directory changes with every release. I've used this:

src_unpack() {
	unpack ${A}
	cd *-${PN}-*
	S=`pwd`
}

In $PORTDIR/sys-fs/udisks-glue/udisks-glue-1.2.0.ebuild to get S=
defined as:

fernandotcl-udisks-glue-f9b4839

Where "f9b4839" changes...


Far as I know, S= isn't used to generate metadata cache, so it's PMS
that need fixing for it's wording:

"All ebuild-defined variables used to generate metadata cache, discussed
in this chapter..."
