Given the assumptions that containers run different distros, including some older ones,
this option is needed.Another thing is, legacy PTYs is a fallback for the case when /dev/pts is not mounted.
Still, my opinion is the feature is from "good to have" department rather than from
"absolutely required".
I can work around it for my environment, but a lot of people will have difficulty if the CONFIG_LEGACY_PTYS option isn't set in the default kernel. Would it be possible for you to add it to the -openvz flavors of the Squeeze kernels as a default?No, it is too late. Also this request should be made through the openvz userspace maintainer.
