mount -U B268042D6803EF43 : invalid option -- 'U'

We read:
   Installing Core to USB pendrives is easily accomplished with Core's
   tc-install extension which is provided on CorePlus. ....
   Tiny Core supports UUID and LABELS.....
   You can mount devices by UUID with the mount command, e.g,
   mount -U 4773-DFE2

Following the instructions:-

$ blkid -s UUID /dev/sda4
/dev/sda4: UUID="B268042D6803EF43"

$ mount -U B268042D6803EF43
mount: invalid option -- 'U'
BusyBox v1.24.2 (2016-05-16 13:23:40 UTC) multi-call binary.

Usage: mount [OPTIONS] [-o OPT] DEVICE NODE

Mount a filesystem. Filesystem autodetection requires /proc.

You're using busybox mount.
You'll need standard mount.
Install util-linux.tcz

OK, thanks. It's only a problem if I don't KNOW why.
Installing extra stuff over the designed minimal could defeat the purpose of TC.

TC is designed to be a tool set to BUILD a system.
It is not intended to run to run as is.
