Don't override exec_prefix= and use --with-rootlibdir to copy runtime libs to /lib while keeping most of the stuff in /usr. With this change, we don't have to override pkgconfig, or manually setup .so symlink. It's also friendlier towards builds with enable-extras (which would require more additional fixes). Enable build of static library, which will enable us to add explicit udev support to static builds of dm/lvm. Adjust start_udev: - remount /dev if it's already mounted (due to initramfs or CONFIG_DEVTMPFS_MOUNT), which allows us to set mount options - add inodes limit safeguard - verify udevd is not running before starting it - remove 'settle' between subsystems/devices Signed-off-by: Michal Soltys <soltys@ziu.info>
