I note that some SCE packaged utilities replace their busybox equivalents while others do not. Is there a reason or is this an error? The following condition is an error.
The xorg-all.sce includes Debian packages for udev and procps. Procps provides versions of ps and pidof. Versions are also provided by busybox. On my system /bin/ps and /bin/pidof are symlinked to busybox; the xorg-all versions are ignored. This is problematic when running the TCE install script (/usr/local/tce.installed/udev) which ultimately calls the udev init script (/etc/init.d/udev). The udev init script requires features of the procps version and fails before ever processing a start, stop, or status command.
Manually removing the busybox links and creating links to the versions in /tmp/tcloop/xorg-all solves the problem (though there are other errors now reported by the script). In addition to ps and pidof, the following utilities in xorg-all also appear to be ignored and unlinked: dmesg, kill, login, more, mount, su, umount.
