Dear Guilhem,
Well when installing a Debian system and enabling encryption in https://anonscm.debian.org/cgit/d-i/partman-crypto.git/, the `panic` kernel parameter will not be automatically added, so I don't think everyone who has enabled full-disk encryption will disable the debug shell. If necessary, I think we should contact the d-i team. More importantly, the claim that the security hole has been fixed by patches, while actually not, is misleading and confusing. I don't think it is appropriate to do actually NOTHING for even a trivial bug; at least we should have a sign noticing the problem here and avoiding unnecessary troubles for future users. Thank you. Regards, XU Guang-zhao
