libguestfs (an LGPLv2+ library) uses the 'hash' module, which turns out to be "GPL". Actually this happened because we started to use it in a separate GPL'd utility program, but later on included this functionality in the core library, copying the same code from the utility but not checking the license of 'hash'. We'd therefore like to request that 'hash' is relicensed as LGPLv2+. If this is not possible, we will have to rewrite the code, probably implementing our own hash table, which would be a shame because hash works well for our needs. Notes: - the code doesn't appear to call exit (it does call abort), and so seems to be suitable for a library - hash-pjw which we also use is already licensed as LGPLv2+ - it looks like the original author was Jim Meyering (CC'd) - the dependencies are all LGPLv2+

It may be time to ask rms if the FSF can do the relicensing, rather than our current policy of tracking down all contributors and asking them to use their grant-back clause of their FSF copyright assignment as our backdoor of not having to involve the FSF.

Is there any final chance this will be relicensed? Hi Rich, Sorry I didn't reply sooner. Somehow I missed this thread completely. libguestfs is definitely a good argument for making hash LGPLv2. I agree to relax its license to LGPLv2, and have just pushed this change:
