Here's my new understanding -- stop me if I've got anything wrong.
(from <....>/rsb/rtems) Doing
../source-builder/sb-set-builder --without-kernel --jobs=none
will build RSB (without the kernel, single threaded) in ./build, then
install it at the prefix, which consists of copying the build to
/d/opt/rtems/4.11. The install has: arm-rtems4.11, bin, include, lib,
libexec, make, and share; which are the required pieces when deploying.
If --bset-tar-file were specified, then the build would be packaged into a
tar file in addition to being installed at the prefix (unless --no-install
were specified). The tar file would contain paths that expect it to be
installed at the specified prefix. To deploy, one would simply copy this
tar file and extract it (accounting for the file path prefix).
--pkg-tar-files will generate tar files for individual packages (e.g. gcc,
binutils). What's the use case for this?
Part of RSB is autoconf and automake, which are built with hardcoded file
paths (the prefix). The environment itself does not need autoconf and
automake to be installed (in the package manager sense) to build RSB.
Autoconf and automake that are built as part of RSB are used to build the
One could specify a prefix that does not exist on computer A, but does
exist on computer B, with --no-install and --bset-tar-file, and the
resulting tar file could be installed at computer B's prefix.

I meant: if RSB is already built and installed without generating a tar
file, will running the sb-set-builder with --bset-tar-file rebuild RSB, or
just package the existing installation?

Is this the bootstrap script that comes in the kernel repository, referred
to in the instructions that say:
./bootstrap -c && ./bootsrtap -p && <...>/source-builder/sb-bootstrap
What would I replace the sb-bootstrap piece with, just "./bootsrtap"?
Is the Windows path on both machines the same? Companies may want to

No, this computer happens to have a small C partition and large D "Data"
partition, and I need to deploy to computers with only the C partition.
Check the cygwin mount command and syntax for details on mounting with

Thanks, mount looks promising, I'll look into it.
In the RSB 4.11.2 documentation (
https://docs.rtems.org/releases/rtems-docs-4.11.2/rsb.pdf) on p18, is the
discussion of install paths and using tar --strip-components a separate
issue from what we've been talking about with automake and autoconf?
