kernel /boot/bzImage quier local=sdb1 noswap waitusb=5
You can remove the
local=sdb1
from your kernel line, then create a directory named tce in the root directory of the pendrive
mkdir /mnt/sdb1/tce
(you might have to use sudo)
Upon reboot, tc will load any *.tce files it finds in that directory and any that you install from the repository will be copied there to be loaded at upon subsequent reboots.
If you happen to have directories named tce in the root directories of other filesystems, you can specify which one to use with
tce=sdb1
on the kernel line, but that's not necessary if you only have one such directory.
Its "quiet", not "quier".
