I find that the files in tce/mydata.tgz are consistently restored during boot, but never backed up during shutdown. The only way to back them up is to manually run $ filetool.sh -b
I'm actually used to this at this point and like it (I'm guaranteed that config files will be identical between reboots unless I change a file and manually run filetool.sh), but I'd like to "troubleshoot" this to understand TCL a little better. Are there any obvious things to check? /opt/shutdown.sh is marked as executable.
