>Description:
In /etc/rc, special care is taken so that portmap will be automatically
enabled if either amd, nfs or nis enabled:
chkdepend amd amd_enable portmap portmap_enable
chkdepend NFS nfs_server_enable portmap portmap_enable
chkdepend NIS nis_server_enable portmap portmap_enable
chkdepend NIS nis_client_enable portmap portmap_enable
Thanks to these lines, variable ${portmap_enable} will be set to "YES"
if needed.
However, /etc/rc later loads /etc/rc.firewall, which unconditionally
reloads /etc/defaults/rc.conf (and /etc/rc.conf, if exists):
if [ -r /etc/defaults/rc.conf ]; then
. /etc/defaults/rc.conf
source_rc_confs
elif [ -r /etc/rc.conf ]; then
. /etc/rc.conf
fi
Thus, unless user specifically set ${portmap_enable} to "YES" in /etc/rc.conf,
${portmap_enable} will be reset to "NO" in /etc/defaults/rc.conf.
Later on, /etc/rc invokes network_pass2() (which defined in /etc/rc.network)
but portmap won't be run because ${portmap_enable} has been reset to "NO".
>How-To-Repeat:
Create /etc/rc.conf as follows:
nfs_server_enable="YES"
And reboot the system. During bootup, rc shows:
DEPENDENCY NOTE: portmap_enable will be enabled to support NFS
However,
% ps ax | grep portmap
produces nothing.
>Fix:
In /etc/rc.firewall, don't reload /etc/rc.conf nor /etc/defaults/rc.conf
if they are already loaded.
/etc/rc.firewall6 already cares this so the same approach can be applied to
/etc/rc.firewall as well. Patch is as follows:
