mount --move . / is missing in switch_root? #557
Description
Hi!
It looks like change c04b565 removes the step of mount(newroot, "/", NULL, MS_MOVE, NULL) and leads to incorrect view of mount point for my systemd init. systemd's component are also somehow affected.
root@ubuntu:~# lsof | grep new_root
systemd-u 633 root cwd DIR 253,1 4096 2 /new_root
systemd-u 633 root rtd DIR 253,1 4096 2 /new_root
systemd-u 633 root txt REG 253,1 723968 133920 /new_root/usr/lib/systemd/systemd-udevd
systemd-u 633 root mem REG 253,1 23958 /new_root/usr/lib/aarch64-linux-gnu/libnss_files-2.31.so (stat: No such file or directory)
Please kindly check this issue.
Thanks!
