I could see running it as root if building and installing on the same computer. In my case the build runs on a PC for an embedded target. There are many files that need to be handled specially by the build environment. In my case this is buildroot, which tries to take care of ownership and permissions when it creates a rootfs.tar. I see that something is testing sudo and the build is interrupted until the users supplies the password. And under some conditions the target directory etc/udev/rules.d is created as being owned by me, other times as being owned by root. When it is owned by me, then the build succeeds. I could make a patch for buildroot to apply to a Xenomai makefile or shell script. But I thought that I should ask before doing this, since we did not experience this problem with xenomai current a couple of months ago.
