Here is a patch for review that adds iPXE.


The licensing is "interesting", see:

https://ipxe.org/licensing

Is that a problem ?


There was no real install target in makefile, so I

added one, any hints on how to write that in a

cleaner way ?


I've put all firmware & rom images in $(out)/bin

Is there a better subdirectory to put such files ?


The double with-directory-excursion could be

handled with a single phase cd'ing into src, but I

can't find where I've seen that...


WDYT ?

Vincent,

Thank you!  Brief review, will build & maybe notice more later:

Could you elaborate?  What's "interesting" about it?  That all 
looks very boring and straightforward to me (which is good! :-) — 
the result is GPL2-only, no?

You can use the GIT-FILE-NAME helper here.

Aside: I'd indent arguments' #:keywords as

+     `(#:phases
+       (modify-phases %standard-phases

to give you more breathing room at deeper indentation levels. 
It's
not needed now, but if someone were to add a new phase they might
                                                            have

                                                            things,
or re-indent the entire thing later, causing noise.  Maybe that's 
just me though.

Interesting approach!  I'm OK with it; looking at ALL it wouldn't 
be more readable or future-proff to use FIND-FILES & Scheme.

/bin is not the right place for these files.  /lib/ipxe looks to 
be the standard; let's use that.

+                  (replace 'build
+                     (lambda _ (with-directory-excursion "src"
+                                 (invoke "make" "-j" 
(number->string
+ 
(parallel-job-count))))))

Let's, instead:

  (add-after 'unpack 'enter-source-directory
    (lambda _ (chdir "src") #t))

Don't worry, the state can't hurt you now.  Now we can keep the 
standard build & install phases.

It might be necessary to add a ‘leave-source-directory’ after 
'install to make sure the licence files are still installed to 
share/doc/.

+       #:tests? #f))
→       #:tests? #f))                    ; no test suite

+    (native-inputs

Nitpick: sort?  :-)

+    (synopsis "PXE-compliant network boot firmware")

I personally like the ‘these are just boot loaders’ angle, but 
would users expect to find this in (gnu packages firmware) 
instead?  Shrug.

+    (license license:gpl2+)))

‘gpl2’ as mentioned above.

If you feel like it (there aren't that many files) you could list 
the licences for each output binary, but that's optional.  The 
combined work appears to be GPL2.

Kind regards,

T G-R

No, there are different makefile targets (rom output filenames) which will
result in different parts of ipxe to be built and included in the output.

There's special makefile targets for each of these targets to determine
the license that applies to each of the latter targets, respectively.

Unfortunately, there's no "all.license" target.

I agree.

I agree.

Does it?  Did you try to make all of the targets' license targets?

P.S. The following ROMs are not reproducible:

10222000.rom GPL2
10500940.rom GPL2 
10ec8139.rom GPL2
15ad07b0.rom GPL2+
1af41000.rom GPL2+
8086100e.mrom GPL2+
8086100f.mrom GPL2+
808610d3.mrom GPL2+
80861209.rom GPL2+
ipxe.iso license checker doesn't work
rtl8139.rom GPL2

which are ALL of them except blib.a, ipxe.dsk, ipxe.lkrn, ipxe.pxe, ipxe.usb
and undionly.kpxe (this one has GPL2+) (which are not roms).

Note: Maybe also pass make-flags to overwrite those:

./Makefile.housekeeping:ECHO_E_BIN_ECHO         := /bin/echo
./Makefile.housekeeping:ECHO_E_BIN_ECHO_E       := /bin/echo -e

OK.  This was already clear.

I'm now convinced that this whole make target thing is a 
misunderstanding and a distraction: iPXE licencing is not, in any 
way, ‘generated on the fly by make rules’ or ‘unclear’ or 
‘interesting’.  It's boring.  It's good.  It's GPL2.

  λ grep -hr '^FILE_LICENCE ( .* );' * | sort -u
  FILE_LICENCE ( BSD2 );
  FILE_LICENCE ( BSD3 );
  FILE_LICENCE ( GPL2_ONLY );
  FILE_LICENCE ( GPL2_OR_LATER );
  FILE_LICENCE ( GPL2_OR_LATER_OR_UBDL );
  FILE_LICENCE ( GPL_ANY );
  FILE_LICENCE ( MIT );
  FILE_LICENCE ( PUBLIC_DOMAIN );

Just a normal Free software package.  Happens to bundle a Perl 
script similar to <https://linux.die.net/man/1/licensecheck> (but 
less useful).  Nothing to see here.

> Did you try to make all of the targets' license targets?

No.  I hope I've shown they're irrelevant now.

What is relevant is that some files are missing licence headers 
(e.g. drivers/net/tg3/tg3_phy.c).  However, this is so common as 
to be standard (Guix wouldn't exist if we demanded headers in 
every file) and COPYING says that these are licenced under ‘the 
GPL’.  That's… acceptable.

Ooh, thanks for catching that.

I noticed that Debian installs a very different set of file( 
name)s[0] than we do.  I don't know what that means though.

Kind regards,

T G-R

The ROMS were easily fixed by setting BUILD_ID_CMD to a static string.

The ISO was a pain.  cdrtools' mkisofs seems to predate the concept of
reproducible builds.  Switching to the modern Xorriso exposed another
bug: we weren't setting ISOLINUX_BIN, and cdrtools' mkisofs happily
created an ISO that probably never worked(?).  Luckily, Xorriso
complained loudly.

The image still isn't reproducible, but it has much fewer dates in it
now and it actually boots ;-) [citation needed].

I've silenced some other annoying warnings during the build, and
applied some of my suggestions from my previous mail (not all though —
please do send a V3).

Neither mtools nor XZ were ever used.  Why were they there?

Kind regards,

I tried it in qemu, got confused by its own ipxe stack, but I

think it then went to isolinux which is from the ipxe.iso image...

This new patch has the following changes:


* used git-file-name


* build everything, as I didn't know what subset to choose


* install everything in ...-ipxe-1.20.1/lib/ipxe with subdirs

for per-arch binaries: bin-i386, etc. You spoke about lib

but put them in share, so I choose to change to the former


* do the install phase in scheme, as it was easier to handle

the above item than to generate a proper makefile target


* only install files with specified extensions, this will get rid

of the .a and other irrelevant files


> Neither mtools nor XZ were ever used.  Why were they there?


I initially added the inputs in bulk from the build instructions

on the website, and forgot to check their usefulness before

sending the patch RFC.

Thanks.

ipxe.iso is not reproducible it seems.

I'll try to have a look, but that's a first for me...


Does this prevent merging ?

The attached patch should be reproducible, it is based on v3 from
Vincent.

It adds the following:
- generate a BUILD_ID based on the package's output hash
- use 'let' to set BUILD_TIMESTAMP
- set some useful options
- add a patch that reset the timestamps of ipxe.iso

Nice and thanks for taking care of this, I've got less time to
contribute lately.

Did you try to upstream the reproducibility patch ?
Should be straightforward enough.

No problem :)

No I didn't submit it to upstream, I got frighten by the answers to a
much smaller patch from a Debian team member about reproduciblity[0][1].
Those threads were useful to make our build reproducible tho.
