RE: [cobalt-users] Raq550: A quick review - I feel like a crash test dummy



We have 2 RAQ550s and have only had one problem with them (a mysterious 
failure of the CCE engine that required a reboot)

If you look at the code Sun wrote for the device in /usr/sausalito, you will 
see why they did the things they did.

1) The "weird" directory structure - they are hashed based on the CCE object 
ID for peformance reasons.
2) /etc/passwd, /etc/shadow not used except for system users - again 
performance reasons, using libpwdb is faster because the users are stored in 
a BTREE DBM file in /var/db instead of a long flat text file.  Less time to 
parse, blah blah.
3) httpd.conf uses the "Include" directive to isolate the vhost stuff.  
Again, reduces the size signficantly of httpd.conf.  I've been using that on 
non cobalt systems for ages.  Works great.
4) meta-verify for the RAQ550 does NOT exist.  According to Sun (I asked this 
same question) it does not use the same database storage mechanism that the 
RAQ4's use to store information.  Again, look through /usr/sasusalito.

I think they hashed the directories and put users in libpwdb because they had 
a lot of clients with a lot of domains and alot of users that complained 
about slowness.

I'm confused about your problems with the "Auto DNS config" - we've been 
using it without a problem for a while (although I agree wholeheartedly it 
should be able to create more records automatically!).  It creates the proper 
DNS entry as long as you enter the proper IP in the config screen.  I don't 
have to delete the "A" record that is created.  However, I do tend to go in 
and create addiotional "mail" CNAME and "MX" records (so really all Auto DNS 
does is create the zone and add the www record)  That's kinda a bummer I 
agree.  It'd be nice to specify in the config to auto create those 
records...that'd be pretty sweet!  However, I haven't had any problems 
entering records into the GUI to create zones.  You can also go in and use 
the .include files to manually add records that the GUI doesn't support.

I'm also confused about why you think it's hard to not use it for a 
simple "hosting machine"?  I've put some non appliance stuff on it without a 
problem or a .pkg file (upgraded DHCP, used MRTG, RedHat Interchange, etc 
etc - simple things yes but "non automatic install" none the less)

I don't work for Sun, I just wanted to point out the reasons they did some 
things.  I've personally never used a RAQ4 so all my (relatively) good 
experiences with the RAQ550 come from it being the only appliances I've ever 
used.  I was actually considering a RAQ4 and kinda wish I had one of both for 
comparison reasons.
