That's great!  Shame about the duplicated effort, but such things 
happen.

file-systems.scm if possible.  linux.scm is already a bloated 
grab-bag.

For now, you can test each package at a time by adding the 
variable (e.g ‘jfs_fsck/static’) as the last line of your current 
.scm file.  This will make the file ‘evaluate to jfs_fsck/static’, 
so you can:

  $ guix build -f thefile.scm

You'll have to change that last line every time you want to change 
the package being built.

You'll need a Guix git checkout to get much further.  If you 
haven't yet done so, read ‘Building from Git’ in the manual and 
bootstrap yourself some Guix.

Then you can copy your 3 package expressions to file-systems.scm, 
keeping it in alphabetical order or at least not making things 
worse.  After making some small adjustments like adding a license: 
prefix, you can build your packages with:

  ~/guix$ ./pre-inst-env guix build jfsutils

Typo that should be the other way 'round?

Are you sure that LDFLAGS=-static is needed when using 
static-package?  Here's my aborted static version:

++(define-public jfsutils/static
++  (static-package
++   (package
++     (inherit jfsutils)
++     (name "jfsutils-static")
++     (inputs
++      `(("util-linux" ,util-linux)
++        ("util-linux:static" ,util-linux "static"))))))

I got my patches from Debian, but they do the same job.  There 
were others[0] but they weren't vital or relevant to Guix.

It will by default remove the ‘build’ dependencies, yes.

I advise against GC'ing unless you desperately need space, and it 
won't come from a handful of relatively tiny stale JFSutils.  Guix 
also deduplicates the store by default.  At file level, even.

Sure.

;; COPYING is gpl3, the headers are gpl2+?

That's interesting.  Where'd you find gpl2+?

Kind regards,
