change login dir

If this is for the root user, here is something I discovered the other day.
root:/root> cd
root:/root> echo $HOME
/root
root:/root> HOME=/
root:/root> cd
root:/> echo $HOME
/
root:/> HOME=/root
root:/> cd
root:/root>
root:/root> HOME=/usr/local/bin
root:/root> cd
root:/usr/local/bin> HOME=/root
root:/usr/local/bin> cd
root:/root>
There is a variable called $HOME. You can modify it to be what ever you want. When you type "cd" <enter> that is where you will go. As in the example above.
You can make this permanent by putting in the bottom of your .profile. export HOME=/some/dir.
This works for any user, even root and application user IDs.
root:/root> cd
root:/root> echo $HOME
/root
root:/root> HOME=/
root:/root> cd
root:/> echo $HOME
/
root:/> HOME=/root
root:/> cd
root:/root>
root:/root> HOME=/usr/local/bin
root:/root> cd
root:/usr/local/bin> HOME=/root
root:/usr/local/bin> cd
root:/root>

systemd-volatile-root.service
SYSTEMD-VOLATILE-ROOT.SERVICE(8) systemd-volatile-root.service SYSTEMD-VOLATILE-ROOT.SERVICE(8) NAME
systemd-volatile-root.service, systemd-volatile-root - Make the root file system volatile SYNOPSIS
systemd-volatile-root.service /lib/systemd/systemd-volatile-root DESCRIPTION
systemd-volatile-root.service is a service that replaces the root directory with a volatile memory file system ("tmpfs"), mounting the original (non-volatile) /usr inside it read-only. This way, vendor data from /usr is available as usual, but all configuration data in /etc, all state data in /var and all other resources stored directly under the root directory are reset on boot and lost at shutdown, enabling fully stateless systems. This service is only enabled if full volatile mode is selected, for example by specifying "systemd.volatile=yes" on the kernel command line. This service runs only in the initial RAM disk ("initrd"), before the system transitions to the host's root directory. Note that this service is not used if "systemd.volatile=state" is used, as in that mode the root directory is non-volatile. SEE ALSO
