I saw (parts of) your talk at debconf on this topic, and was happy to see the results you were getting. Are your slides on the web somewhere? I was a bit surprised that parallel execution only shaved 2 seconds of the boot, but suspect it might be because of inefficient implementation in /etc/init.d/rc. > To make this speed up available to everyone, we have 2 main choices: > > 1. Make /bin/sh point to /bin/dash Debian-edu has been doing this since woody, to avoid bash blocking the umount of /usr/ when nss_ldap is being used (bug #120340). We have not experienced any serious problems with it, and all the minor problems we have seen have been fixed quickly. I believe this is a fairly safe thing to do, but believe it should be done shortly after etch releases, and not just a few months before we freeze for etch. There are other things we can manage before etch releases (avoid external programs, use dynamic readahead, parallel booting, etc), and I suggest we focus on them this summer, and switch to dash next spring. :) Friendly, -- Petter Reinholdtsen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
