please add `enewuser` and `enewgroup` to the squid ebuilds so we can remove them from baselayout's passwd/group
fixed by adding squid user/group in pkg_setup & pkg_preinst, using UID 31 (for correct installation of bin packages). please take a look at bug #94745. since squid cannot be a dependency of system, the ebuild could create its own user/group without problems. on the contrary, net-proxy/dante could be a dependency of system (by adding socks5 useflag) which means it cannot safely create its own user (safely == dante is instaled *after* shadow).
