[systemd-devel] Systemd license vs. libcryptsetup license

[Krzysztof Jackiewicz]

I guess the "conflict" was not the best word to describe it. 

If I want to release a product with systemd the libryptsetup option will
force me to release it under GPL. Is that correct?

Thanks,

Krzy

A license conflict appears when two pieces of software are combined and the
licenses have incompatible terms, so they cannot be both satisfied at the
same time. Systemd is LGPL which is compatible with GPL and pretty much
anything else. Also, we don't distribute the combined product, which is the
only thing LGPL and GPL put any conditions on.
