Given the ROM exception in GPLv3, I guess you could seal and anti-tamper it as much as you want, and leave the ROM at such a place in which it's easily replaceable but with signature checking and all such that the user doesn't install ROM that is not authorized by you. This would be against the spirit of the GPL, but I don't know whether it could be interpreted as disrespecting some other provision of the letter of GPLv3. Maybe it could. Something for lawyers to decide, and IANAL. Something the GPLv3 folks would like to take into account, even if the outcome may be not quite what you'd like ;-) Thanks again for the information, -- Alexandre Oliva http://www.lsd.ic.unicamp.br/~oliva/ FSF Latin America Board Member http://www.fsfla.org/ Red Hat Compiler Engineer aoliva@{redhat.com, gcc.gnu.org} Free Software Evangelist oliva@{lsd.ic.unicamp.br, gnu.org} - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
