This prevented the vservers to load on boot (which i actually want and need but disabled to see what's going on). I then rebooted and started a vserver manually and instead of the startup lines zipping by it took ages for it to print some lines so now i knew Starting vservers of type default... was actually not hanging my computer but rather just going very very slow. which lines? i suspect they are the ones about various network connections for your vserver (trying to resolve hostname, for example). I started all my vservers and after about 10 minutes (i had started an uml to get DNS going) i decided to shut down the uml that provided dns and start the vserver instead that also provides dns. Well, to my surprise, that one started quickly again. Entering the vservers was also quick again. Very strange. no - you now have your dns working, hence it doesn't need to wait for network timeouts.

I have my DNS inside a vserver, so the DNS vserver should be started as early as possible. How do i do that if the links above aren't valid?

I'm looking at it right now and trying a vhashify on one of my _less_ strategic guests. Ie. it can be replaced. :-) I thought I had all the pieces in place but got these three errors: error: cannot open Packages index using db3 - No such file or directory (2) error: cannot open Packages database in /var/lib/rpm Duplicate hash-dir entry '0' found The first might be the RPM move from Berkley db version 3 to version 4 and so version 3 doesn't get installed. A quick check with rpm shows only db4. Bug in vhashify or in some RPM libraries is is using? The second is strange ( unless it is related to the first. ) There are RPM databases in /var/lib/rpm . The last I can figure out as somehow both a '0' and '00' got created in the '/etc/vservers/.defaults/apps/vunify/hash/' directory. I did the 0 and the 00 got ( by date stamp ) created last week when I was building a 'new' guest. So the error is probably coming from the vhashify binary having trouble by treating the '0' and '00' as numeric instead of as alphanumeric.

Thing is that i'm not sure on how to do it correctly on Debian. I have a util-vserver script in /etc/init.d which is linked to from rc2.d: S23util-vserver - ../init.d/util-vserver please check my reply to the original question, it is probably the much better solution if you 'just' require a proper order of course, the different runlevel scripts make perfect sense if you actually _use_ different runlevels for your host system In /etc/default/util-vserver i reread this comment: # The vserver initscript runs late in the boot-up sequence, which may # be inappropriate for services that need to run earlier, such as # nameservers or VPN tunnels. If a copy of the initscript is made to # run at an earlier position, you can then set $MARK to be those vservers # that you want to run then. #MARK=default This is confusing to me. The comment says to copy the initscript for those servers that need to be started earlier but the script looks at /etc/default/util-vserver to find info on what servers to start first. So how do i do that? I could copy the script, copy /etc/default/util-vserver and adjust the MARK AUTO parameters there but i don't think that's the proper way to deal with this problem or is it? Looking at the /etc/init.d/util-vserver script (added as extra info below), i could make a copy and then put this code in comment DEBIANCONFIG=/etc/default/util-vserver if [ -f $DEBIANCONFIG ] then . $DEBIANCONFIG fi Then add MARK AUTO in there. For instance, MARK=dnsserver AUTO=true Next make a link to this script from /etc/rc2.d at an early stage. Is this how it should be done? best, Herbert Thanks, Benedict [more stuff zapped] ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
