From: Yann E. MORIN Date: Tue, 1 Aug 2017 22:52:12 +0000 (+0200) Subject: package/skeleton: split out into skeleton-custom X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0c750a027b720e316b9d7fccabb4d86bb2856ec0;p=buildroot.git package/skeleton: split out into skeleton-custom For the custom skeleton, we practicaly do nothing, except ensure it contains the basic, required directories, and that those are properly setup wrt. merged /usr. Furthermore, our current skeleton is not fit for systemd, and we'll have to split things out into various skeletons. So, off-load the custom skeleton into its own package. Thus, the existing skeleton package is now limited to: - when using our default skeleton, install and tweak it properly; - when using a custom skeleton, do nothing except for depending on the skeleton-custom package.
