[sf-lug] About USB partitioning and formatting

some weeks ago i posted a question about making
a USB stick bootable. i was hoping for something
along the lines of using the dd command along
with info as to what corresponds to "partitions"
and "cylinders" and such in USB stick land.
the following link is real good: tells a lot
about essential storage technology of USB sticks
(and SD and other NAND flash storage devices).
essentially, what i got out of it after one
reading (two or more readings to go) is
* don't use fdisk to partition a USB stick
* don't use mkfs to put a filesystem on a USB stick
the following seems good, if not best, practice:
just put up with whatever FAT-style filesystem
is on the stick, don't count on symlinks or inode
tables; tarballs might be a good way to preserve
no partitions on a single stick: buy a separate
stick for each partition you want to copy.
to make a USB stick bootable, stick with syslinux
or some other software specialized for working with
i am, of course, interested in how my surmises
are wrong-headed and what might be misinformation
or omissions from the linked page.
