This commit uses `warn()` to notify the user if sandbox setup fails with errno==EPERM and /proc/sys/user/max_user_namespaces is missing or zero, since that is at least part of the reason why sandbox setup failed. Note that `echo -n 0 > /proc/sys/user/max_user_namespaces` or equivalent at boot time has been the recommended mitigation for several Linux LPE vulnerabilities over the past few years. Many users have applied this mitigation and then forgotten that they have done so. |
