Hi, folks:
I am dealing with a problem, which is to use a overlay filesystem as the
new root after the root system boot up. I am freshman on systemd service, so
can anyone help me on my script errors? why it's failed?
My service file, i put it under /usr/lib/systemd/system:
>>>>>>
[Unit]Description=Change root to
overlayAfter=systemd-remount-fs.serviceConditionKernelCommandLine=|systemd.setenv
[Service]TimeoutStartSec=0ExecStart=/usr/local/bin/ovl_chroot.sh
[Install]WantedBy=local-fs.target
>>>>
My bash script for changing root filesystem
>>>>#!/bin/bash echo "Start to mount overlay and change root to overlay" if [ !
>>>>-d /ovl_root/test1 ] ;then mkdir -p /ovl_root mkdir -p
>>>>/ovl_root/test1 cd /ovl_root/test1 mkdir -p root mkdir -p work
>>>>mkdir -p upperfi mount -t overlay overlay
>>>>-olowerdir=/,upperdir=/ovl_root/test1/upper,workdir=/ovl_root/test1/work
>>>>/ovl_root/test1/root cd /ovl_root/test1/root /usr/sbin/chroot
>>>>/ovl_root/test1/root >>>
This is the output of the status
>>>>

But i run the script in the shell, it can change root to the specify directory.
Anyone has any ideas?
Thank you very muchXun
