postfix-nochroot(8) System Manager's Manual postfix-nochroot(8)NAME
postfix-nochroot - change /etc/postfix/master.cf to not use chroot
SYNOPSIS
postfix-nochroot
DESCRIPTION
Renames /etc/postfix/master.cf to /etc/postfix/master.cf.bak and creates a new /etc/postfix/master.cf file with every service configured to
not use chroot. Every modified line is commented. It also restarts Postfix (to apply the change) and rmoves the unused chroot directories
/var/spool/postfix/{etc,lib,usr} .
Using a chroot environment makes upgrades more difficult and gets in the way when running SE Linux (without actually providing any security
benefit in a SE Linux system).
