And while we're at it, use a more sustainable way of getting the
address of the next file to be written to.
Since builder-hex0 doesn't distinguish directories from zero-length
files, this has a limitation that it won't copy any zero-length
files or empty directories. Only one such file is important for the
bootstrap process (mes/config.h), which is recreated using an
improve step.
By wrapping $(cat) in an eval, redirections and other advanced
syntax can now work in the early prompts.
Also, since "set -E" is broken is the early bash, fall back to
using "set -e" and an EXIT trap, until we can upgrade to a bash
version that already has working "set -E", or perhaps backport
it to 2.05b.
When renaming using_bash to bash_build, I accidentally removed the
+ sign from the assignment, causing bash_build > 1 to never match,
resulting in old-style Ctrl+D traps even in the new Bash.
This patch restores the intended += behavior.
This adds a new flag, -i / --interactive, which enables opening a
Bash prompt whenever something goes wrong in the bootstrap. This is
highly useful when developing or debugging live-bootstrap, but it
needs to be off by default, for use in automated processes.
In the future, asking for variables at runtime could (and perhaps
should) also be gated behind this flag.
- This idea originates from very early in the project and was, at the
time, a very easy way to categorise things.
- Now, it doesn't really make much sense - it is fairly arbitary, often
occuring when there is a change in kernel, but not from builder-hex0
to fiwix, and sysb is in reality completely unnecessary.
- In short, the sys* stuff is a bit of a mess that makes the project
more difficult to understand.
- This puts everything down into one folder and has a manifest file that
is used to generate the build scripts on the fly rather than using
coded scripts.
- This is created in the "seed" stage.
stage0-posix -- (calls) --> seed -- (generates) --> main steps
Alongside this change there are a variety of other smaller fixups to the
general structure of the live-bootstrap rootfs.
- Creating a rootfs has become much simpler and is defined as code in
go.sh. The new structure, for an about-to-be booted system, is
/
-- /steps (direct copy of steps/)
-- /distfiles (direct copy of distfiles/)
-- all files from seed/*
-- all files from seed/stage0-posix/*
- There is no longer such a thing as /usr/include/musl, this didn't
really make any sense, as musl is the final libc used. Rather, to
separate musl and mes, we have /usr/include/mes, which is much easier
to work with.
- This also makes mes easier to blow away later.
- A few things that weren't properly in packages have been changed;
checksum-transcriber, simple-patch, kexec-fiwix have all been given
fully qualified package names.
- Highly breaking change, scripts now exist in their package directory
but NOT WITH THE packagename.sh. Rather, they use pass1.sh, pass2.sh,
etc. This avoids manual definition of passes.
- Ditto with patches; default directory is patches, but then any patch
series specific to a pass are named patches-passX.
