For virgin "X" system (kernel+initrd, set tce=, import Xprogs, flwm_topside, wbar, xorg-all), adding "user=craig" boot code causes errors loading flwm_topside and wbar. Relevant boot messages:
Loading Extensions...
Xprogs touch: /usr/local/tce.installed/flwm_topside : Permission denied.
flwm_topside touch: /usr/local/tce.installed/wbar: Permission denied.
wbar
Note: xorg-all was NOT in sceboot.lst to be able to see the boot messages (as xorg-all writes directly to /dev/console, not redirected).
