If that's what you want to do, OpenWrt will act just like any other
UNIX-like system out there. Just use the 'mount' and 'umount' commands
then, you may also use /etc/fstab, of course.

OP was asking about the 'block umount' command, which is anyway
specific to OpenWrt, and used for specific use-cases such as
automatically creating mountpoints, automatically mounting devices on
insertion, unmounting them on removal, ...
It is configured in /etc/config/fstab (and *not* /etc/fstab).

Also with regard to top-posting OpenWrt is not that different from
most other UNIX-related communities. Just don't do it ;)
