Full Discussion: How do I run my "SMTP" service as a root privilege ?
Operating Systems Linux Red Hat How do I run my "SMTP" service as a root privilege ? Post 302332676 by mark54g on Thursday 9th of July 2009 09:33:55 PM

I would not recommend having a listening service run as root. Sendmail had many security flaws as a result of it being so monolithic. Postfix tends to skirt around that better with a modular approach and not being root.

What are you trying to accomplish? Sometimes, cutting off the intended implementation is a misunderstanding of what you need to do to reach what you want to happen.

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.
