I have successfully migrated a RHEL 6 based OS from Upstart to systemd, using the RHEL6 «2.6.32» kernel. I basically had to apply three patches to the RHEL6 kernel for systemd to boot properly: - the patch to move the cgroups hierarchy to /sys/fr/cgroup: 676db4af043014e852f67ba0349dae0071bd11f3 - the patch to have printk not mangle the syslog prefixes (this one is optional): 9d90c8d9cde929cbc575098e825d7c29d9f45054 - the patch to add the 'active' sysfs attribute to tty0 and console: fbc92a3455577ab17615cbcb91826399061bd789 You can find those changesets in the linux-2.6 git tree, only the third one took a bit of work to rebase. After building an otherwise «vanilla» RHEL6 kernel with those three patches applied, everything seems to work perfectly fine with systemd 32 (although I have to admit I haven't really tested the more recent parts such as the logind or hostnamed stuff). -- Mathieu _______________________________________________ systemd-devel mailing list firstname.lastname@example.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
