(1) The stock sendmail.cf will only listen on the loopback interface.
(2) The stock submit.cf specifally connects to "localhost." which
should be less susceptible to being confused or looking confused.
(3) The smtp listener starts by default, if needed. The setting in
/etc/default/rc.conf is still "no", but rc.d/sendmail detects the
default setting and will change it to yes if need is determined.
Need is defined as "nothing else seems to have been changed about the
mail configuration but we'd like locally originated and locally
destined mail to be delivered". If you change, eg, mailer.conf to
point to postfix or some other MTA, sendmail will not start.
at boot automatically, so a machine dual booting another OS that uses
the RTC at localtime and NetBSD agree on the current time even if daylight
saving started/ended (without recompiling a kernel twice per year).
Awk code by Matt Thomas.
rc_rcorder_flags extra flags to rcorder(8) in /etc/rc
rcshutdown_rcorder_flags extra flags to rcorder(8) in /etc/rc.shutdown
This can be used to specify extra directories to search for rc.d scripts in.
For example, adding the following to rc.conf(5):
rc_rcorder_flags="/usr/pkg/etc/rc.d/*"
rcshutdown_rcorder_flags="/usr/pkg/etc/rc.d/*"
will add the files in /usr/pkg/etc/rc.d to the list of files that rcorder(8)
uses to build the list of scripts to start or stop.
I proposed this functionality on tech-userlevel@ over one month ago.
Closes the recent [misc/16888], which asked for a similar feature.
Replace $critical_filesystems with $critical_filesystems_remote .
The new names are now consistent with the type argument that
mount_critical_filesystems() is called with, and allows for other types to
be easily supported by that function.
For backwards compatibility purposes, if the now obsolete variable is defined
(even empty), it takes precedence over the new form, and you will be warned.
If you want to stop the warnings, update your rc.conf(5) settings!
If set to yes, block-type swap partitions will be deleted upon shutdown.
This can be useful if swapping onto a RAIDframe device, but may cause
unnecessary delays during shutdown for the general case, so it's
disabled by default.
Should resolve [bin/14433] and [kern/14769].
keep state to be locked (modification prevented) and then saved to disk,
allowing for the system to experience a reboot, followed by the restoration
of that information, resulting in connections not being interrupted.
To activate this feature, set ipfs=YES in /etc/rc.conf
enabled by setting $rcshutdown_timeout to a number of seconds to wait for
before terminating rc.shutdown. This is disabled by default.
- Use symbolic names rather than numbers when defining a trap.
- Improve some comments.
