[gentoo-dev] [PATCH] fcaps.eclass: support EAPI 8

[David Michael]

This defines the native install-time libcap dependency as:

  - EAPI < 7: RDEPEND
        Only regular ROOT=/ builds can be expected to work.

  - EAPI = 7: RDEPEND + BDEPEND
        Also install the native setcap at built time, so cross-
        compiling will work, but not installing binpkgs in ROOTs.

  - EAPI > 7: IDEPEND
        Install native setcap at install-time; it works everywhere.

Since all remaining users are EAPI 6 and above, declare eclass
compatibility with EAPIs 6, 7, and 8.

Hi,

This is from https://github.com/gentoo/gentoo/pull/21239 .

I noticed a note in the PMS about how ebuilds with later EAPIs should be
remain source-able by old package managers for EAPI parsing.  Does that
extend to eclasses?  It would seem unfortunate for global scope to be
permanently restricted to bash 3.0 syntax.

Thanks.

David
