(Sorry for the delay, I was out for vacation)

The last part of the script ./make-memstick.sh which should produce the final
image, but the processes mkimg never end, is:


...
# Make an ESP in a file.
espfilename=$(mktemp /tmp/efiboot.XXXXXX)
make_esp_file ${espfilename} ${fat32min} ${BASEBITSDIR}/boot/loader.efi

mkimg -s mbr \
    -b ${BASEBITSDIR}/boot/mbr \
    -p efi:=${espfilename} \
    -p freebsd:-"mkimg -s bsd -b ${BASEBITSDIR}/boot/boot -p freebsd-ufs:=${2}.part" \
    -a 2 \
    -o ${2}
...

I've split the two processes, connected my the pipe, and run them one
after the other as:


#!/bin/sh

# set -x

BASEBITSDIR=/home/guru/140.root
img=/home/guru/zdata/memstick.img

espfilename=/home/guru/zdata/efiboot.7S9yjL

mkimg -s bsd -b ${BASEBITSDIR}/boot/boot \
      -p freebsd-ufs:=${img}.part > ${img}.part.mkimg

mkimg -s mbr \
    -b ${BASEBITSDIR}/boot/mbr \
    -p efi:=${espfilename} \
    -p freebsd:=${img}.part.mkimg \
    -a 2 \
    -o ${img}

# ls -l /home/guru/zdata
# -rw-r--r--  1 root wheel 23795073024 Sep  3 17:12 memstick.img.part
# -rw-------  1 root wheel    34091008 Sep  3 17:12 efiboot.7S9yjL
# -rw-r--r--  1 root wheel 23795081216 Sep  3 18:25 memstick.img.part.mkimg
# -rw-r--r--  1 root wheel 23829172736 Sep  3 18:34 memstick.img

The resulting file 'memstick.img' (copied with dd to an USB key)
boots fine.

Now I'm clueless about why the pipe between

mkimg ... -p freebsd:-"mkimg -s bsd ..." ...

does not work as it should.
