/etc/logadm.conf gets rewritten bug

Question

I think I found a race condition in logadm that makes can corrupt the conf file. Firstly, let me say that any utility that expects to update a timestamp in a running conf file is asking for trouble. The utility should be "selfhealing" and the conf file should be untouchable with a separate status/timestamp file.
So I have a system running :
SunOS XXXXXX 5.9 Generic_118558-27 sun4u sparc SUNW,Sun-Fire
At the same cron time, it calls:
0 3 * * * /usr/sbin/logadm
and
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /bin/rm /var/adm/pacct.[0-9]*;/usr/lib/acct/turnacct switch
At 3 am, both would be called. "turnacct switch" calls "logadm -p now /var/adm/pacct".
There must be insufficient locking or no locking because the result on my system is only the pacct record in /etc/logadm.conf; the previous standard entries are all lost in /etc/logadm.conf.
Result in /etc/logadm.conf:
/var/adm/pacct -P 'Fri Jul 6 15:50:00 2007'
The fix is to offset the running of logadm by a minute or two in cron. The real fix would be to rewrite with correct file locking.

also, could i suggest adding entries for opendns to your /etc/resolv.conf.tail after your local one?
domain myhome.westell.com
nameserver 192.168.1.1
nameserver 208.67.222.222 #opendns
nameserver 208.67.220.220 #opendns
works nicely as a backup if your somewhere with a dodgy dns etc
Yep, I just tried and it works fine when I use nslookup but web browser and ping still dont work. I can use googles ip 74.125.53.100 and everything works, but not the domain name.  As for opendns Id really just like to get my standard dns to work for now, I know it should work because I use it on all the other computers plus it works with dhcp. After I figure out what Im doing and whats going wrong Im probably going to setup my router to use opendns.
[tj@arch ~]$ nslookup google.com 192.168.1.1
Server: 192.168.1.1
Address: 192.168.1.1#53
Non-authoritative answer:
Name: google.com
Address: 74.125.53.100
Name: google.com
Address: 74.125.67.100
Name: google.com
Address: 74.125.45.100
[tj@arch ~]$
I still havn't got around to seeing if I can get it to work with netcfg, it was late last night and I fell asleep. Ill try it now and post back with the results.
