File 0176-Parse-rootflags-correctly.patch of Package dracut.376

From d15ca6119125b015bddb2919b898b4d0e2aeccbf Mon Sep 17 00:00:00 2001

Subject: Parse rootflags correctly

The patch removes systemd-fstab-generator for the system-generators
directory so that it won't get started automatically.
It will be called by dracut-rootfs-generator if root= and rootflags=
are given at the command line.
Otherwise, dracut-rootfs-generator will create the sysroot.mount unit.
and sets the mount of /sysroot to readonly.
