Yep
The specific command I was attempting to run was
@reboot (run script) > /mnt/us/log
I ran the script independently so I know that part worked just fine but it wouldn't run it when I edited /etc/crontabs/root to run the script, nor would it log the file (just for the record I tried with and without trying to log the event)
@lumanz were you also editing the crontabs folder, or were you editing it elsewhere? Were you also doing @reboot?
Oh, and I also tried having it run the command in the script directly rather than having it call a script to run
