Don't know if that's still the case.

ah, now *that* i like ... of course, i'd probably use a here
document:
sfdisk ${DEVICE} <<-EOF
label: dos
start=1MiB size=32MiB type=0x0C bootable
start=33MiB"
EOF
pretty sure that would have the same effect, yes?

sfdisk has changed both its input format and command-line options in
recent versions of util-linux. If you're scripting sfdisk, you need to
be aware of this as some of the people who use your scripts will have
varying versions of util-linux. For example, in my experience,
util-linux 2.28 in Debian Stretch and util-linux 2.25.2 in Debian Jessie
cannot have their sfdisk executables scripted in the same way and then
produce the same set of partitions when setting up an SD card for an
embedded system.
The change in input format and command-line options happened around
util-linux 2.26-2.27 but I haven't dug into it too much to find out
exactly when.
The newer input format for sfdisk is quite nice, imho, and easy to read.
You can do something like this now:
{
echo "label: dos"
echo "start=1MiB size=32MiB type=0x0C bootable"
echo "start=33MiB"
} | sfdisk ${DEVICE}
While the older sfdisk input format would look something like:
{
echo 1,32,0x0C,*
echo 33,,,-
} | sfdisk ${DEVICE}
Thanks,
Andrew
