You can write a small script that parses /proc/misc and creates the device,
like
# /sbin/mknod /dev/kvm c 10 `grep '<kvm>' /proc/misc | cut -f 1 -d `
If you already have an init script, e.g. to set up tun/tap devices,
it would make sense to put it in there.
09 Jan 10 Apple Computer › Wiki › ubuntuusers.de
Apple setzte vor 2006 PowerPC-Prozessoren ein, danach wurde die Prozessorarchitektur auf Intel-Prozessoren umgestellt. Seitdem ist die Installation von alternativen Betriebssystemen auf Apple-Rechnern sehr viel leichter geworden. Da Apple über die Systemaktualisierung auch Firmware-Upgrades verteilt, ist es ratsam, das hauseigene Betriebssystem Mac OS X nicht komplett zu entfernen. Durch die grundsätzliche Unterstützung von Windows ist bei den neueren Macs mit Intelprozessoren auch ein Tripleboot denkbar.Die Installation von Ubuntu auf einem PowerPC-Mac unterscheidet sich hingegen etwas von der Installation auf einem normalen PC. Insbesondere bei Erstellung eines Dualboot-Systems mit Ubuntu und Mac OS X sind einige Besonderheiten zu beachten, um ein funktionierendes System zu erhalten und Datenverlusten vorzubeugen. Dabei müssen einige Vorbereitungen getroffen werden, damit die Verkleinerung der Festplattenpartition sowie die Installation des Bootloaders yaboot problemlos klappt.11 Dez 09 “Couldn’t load XPCOM” after Firefox upgrade « ewald.tienkamp.nl

You might know the situation: You’d like to run tomcat from a privileged port, but the bloody thing just won’t start. Of course, it’s java-specific. Usually, a daemon gets its port from root. Not with Java. Your possibilities are therefore … Continue reading28 Aug 08 creating apache vhosts with style
We decided to have a reverse domain name structure that conatains (beside the htdocs) all vhost-related information like logs, stats and config. The reverse structure is neccessary to get an quick overview not about the subdomains but the domains. Additionally, … Continue reading30 Jul 08 recursive md5 hashing with Linux
The problem: You need a md5sum of a directory. Unfortunately, md5sum just accepts files as input. The solution: Let’s use find! Okay. Here we go: find DIRECTORY -type f -exec md5sum ‘{}’ \; | md5sum – | awk ‘{print $1}’ … Continue reading
