Comparing 'last-before-rc1-april-rolling' and RC1, rolling does not contains '/etc/polkit-1' dir when unpacking cat'ed from 4 parts rootfs. This directory created after system loaded.
'/etc/polkit-1/localauthority/90-mandatory.d/org.freedesktop.udisks2.pkla' where is disk group option located, presents in both versions after system boot.
But 'polkitd' is even NOT in process list with RC1. (I know about show root tasks in lxtask.) Now running old-rolling and I can't find from where it starting. Text search from midnight commander gives no result. Also in RC1 a lot of files, using while booting (in /etc) are smaller (size in bytes).
