using etcupdate to update jail

[dvl@]

I'm using FreeBSD 9.3 and ezjail on the host to run several jails.

I want to try etcupdate(8) (instead of mergemaster(8)) to see how that goes.

/usr/src on the host contains the 9.3-RELEASE source code.

I want to update the jail located at /usr/jails/snapshots.

First, I tried this command:

$ sudo etcupdate -D /usr/jails/snapshots -F -A "/etc/mail/sendmail.cf /etc/periodic/* \
    /etc/bluetooth* /etc/pam.d/* /etc/rc.d/* /etc/security/*"
No previous tree to compare against, a sane comparison is not possible.

Next attempt:

$ sudo etcupdate extract -D /usr/jails/snapshots  -F -A "/etc/mail/sendmail.cf /etc/periodic/* \
   /etc/bluetooth* /etc/pam.d/* /etc/rc.d/* /etc/security/*"
$

To confirm this had done the right thing, I looked for include, a new feature in /etc/newsyslog.conf. It was not there:

$ grep include  /usr/jails/snapshots/etc/newsyslog.conf
# rotated, then the entry for that file should include the 'N' flag.
$

OK, what's the status?

$ sudo etcupdate status -D /usr/jails/snapshots
$

Hmmm. What about this:

$ sudo etcupdate diff -D /usr/jails/snapshots  | less

Removed: /etc/libmap.conf

Conclusion: etcupdate(8) knows what to do, but I can't make it do it.
