I'm looking into the possibility of generating deltaisos directly on alt.fp.o, which runs RHEL 5.6, rather than downloading the ISOs, creating the disos, then uploading them. This would make it possible to post the disos much sooner as my connection is 3/768 DSL and most of the time involved is in the download/upload. In addition, alt.fp.o has 8 cores, so it would be possible to use 2 of them simultaneously. (The programs I need, makedeltaiso and applydeltaiso, are single-threaded.)
The possibilities I'm aware of are either creating static executables or using a chroot environment (the first seems preferable, if possible). Can anyone give any pointers? Thanks.

If EPEL[1] is installed, then a yum install deltaiso should get them for the admin.

The machine only has the old xz compression library (liblzma.so.0). The F15 versions of {make,apply}deltaiso require the new library (liblzma.so.5) to rebuild F15 ISOs, so I can't use the EPEL version. It would have worked for disos for F14 and below.

Its not at all possible, glibc in f15 requires that the host be running 2.6.32 or newer kernel, and its running 2.6.18.

I've found by just attempting to run the F14 and F15 {make,apply}deltaiso executables that the F14 version of makedeltaiso seems to work normally, though F14's applydeltaiso complains:
applydeltaiso_f14: /lib64/libc.so.6: version `GLIBC_2.7' not found (required by applydeltaiso_f14)
The F15 versions both fail due to the missing liblzma.so.5, as expected. Would the difference between F14's glibc-2.13-1 and F15's glibc-2.13.90-8 make F15's makedeltaiso fail even if liblzma.so.5 was installed? Just getting that to work would save quite a bit of time. Ideally, I'd like to find a way to make this work without any such outside support, though.

You only need the liblzma bits to be static. I think the following should work
1. Install the F15 xz-5 source rpm and prepare it for building (rpmbuild -bp) 2. Go into the xz-5 build directory and run make 3. Install the F15 deltarpm source rpm and prepare it for building (rpmbuild -bp) 4. Go into the deltarpm build directory and edit the Makefile to use the lzma headers and archive you just built - with something like the patch below 5. make 6. Test the applydeltaiao and makdeltaiso files to see if they work.

I did what you described on a F15 machine, and it works! Thank you. These could also be used in place of the F14 compression upgrade hack, so I'll probably post them on my fedorapeople site. I don't understand why they both work, though - the F14 version of applydeltaiso failed with
applydeltaiso_f14: /lib64/libc.so.6: version `GLIBC_2.7' not found (required by applydeltaiso_f14)
so why does this version work, given that it was built on F15, without libc.so.6 being static?
I'm working now on trying to get a version of metalink that will run on alt.fp.o. There is no metalink package in the RHEL repos, and running F14's metalink gives the error
metalink_f14: error while loading shared libraries: libglibmm-2.4.so.1: cannot open shared object file: No such file or directory
and this library is included in the glibmm24 package, which IS in the EPEL repo, but not installed. I'm trying to use your procedure with xz -> glibmm24 and deltarpm -> metalink, but unfortunately metalink's Makefile is much more complicated than deltarpm's (being generated by ./configure) so it's difficult to figure out the proper edit. But this is much less important than the deltaiso executables anyway.
