Python script to create packages, sane?

Hi Everyone,
OBuname:
FreeBSD 6.1-RELEASE-p3 #0: Tue Aug 22 22:42:18 EDT 2006 root@localhost:/usr/obj/usr/src/sys/THE i386
I'm been working with and learning the ports and packages
system. I enjoy the challenge because this stuff can get
awfully vexing every now and then.
I just finished running 'portmanager -u -f -l' after
several days (with a little 'portmanager -u -f -l --resume'
every now and then). I have this nicely up-to-date large (450+)
set of ports installed. It cost a lot in terms of time.
So I want to take all these installed ports and build
packages out of them. Enter the following python program:
====================== 8< ===================
#!/usr/bin/env python
# make_package.py
#
# Script to create packages for currently installed ports/packages.
# Uses pkg_create with the -b option.
# It will build packages in the current working directory so a
# 'cd /usr/ports/packages/All' command would be useful before
# running it.
#
# Usage: script make_package.log && make_package.py /var/db/pkg/*
#
# needed modules
import sys, os
pkg_create = "/usr/sbin/pkg_create"
print '==========='
dash_b = '-b'
for name in sys.argv[1:]:
# print ":: ", name
pkg_name = name.split('/')[-1]
print "Installed package:", pkg_name
# run pkg_create command, capture errors but don't stop
print "Command: ", pkg_create, dash_b, pkg_name
status = os.spawnv(os.P_WAIT, pkg_create, [pkg_create, dash_b, pkg_name])
print "Status:", status
====================== 8< ===================
The results of running it are encouraging:
# cd /usr/ports/packages/All
# script make_packages.log
Script started, output file is make_packages.log
# ~/bin/make_packages.py /var/db/pkg/*

==================
I've seen the last few types of errors with
package creation before. I was using both portupgrade
and 'make package' commands when I encountered such
errors. To fix them is to simply force re-installation
of the port in question. No big deal.
A brief directory listing shows fresh packages:
/usr/ports/packages/All# ls -lat | more
total 3019778
-rw-r--r-- 1 root ports 48352 Dec 30 02:21 make_packages.log
-rw-r--r-- 1 root ports 13217116 Dec 30 02:21 zope-3.3.0.tgz
drwxr-xr-x 2 root ports 29184 Dec 29 18:33 .
-rw-r--r-- 1 root ports 1410567 Dec 29 18:33 xorg-vfbserver-6.9.0_2.tgz
-rw-r--r-- 1 root ports 176158 Dec 29 18:33 xterm-223.tgz
-rw-r--r-- 1 root ports 423100 Dec 29 18:33 xvid-1.1.2,1.tgz
[...]
To make a long story short and actually ask a question, will
building packages this way make proper packages? Am I doing
something fundamentally wrong in this approach? I'd like to
simply use the generated packages as a local repository for the
other FreeBSD systems I use.
Thanks for any comments.
Vinny
