The attached patch modifies the daemontools ebuild to use dietlibc (instead of glibc) if the (new) USE flag 'dietlibc' is set. Please add this line to /usr/portage/profiles/use.desc after applying the patch: dietlibc - link against dietlibc (a stripped-down glibc replacement)
Created attachment 4179 [details, diff] patch for sys-apps/daemontools/daemontools-0.76-r1.ebuild
