Initramfs mount root manually

Instead delete everything out of rootfs to free up the space (find -xdev / -exec rm ‘{}’ ‘;’), overmount rootfs with the new root (cd /newmount; mount –move. /; chroot.), attach stdin/stdout/stderr to the new /dev/console, and exec the new init. # Mount the root filesystem. mount -o ro /dev/sda1 /mnt/root # Clean up. umount /proc umount /sys # Boot the real thing. exec switch_root /mnt/root /sbin/init This example needs some device nodes to work, mainly the root block device.  · Without manually adding new packages, the base, But I can’t mount initramfs, because I need the OS-release file in /sysroot.
