[pve-devel] [PATCH container v2 2/2] pct: add keep-env option

[Folke Gleumes <f.gleumes@proxmox.com>]

The keep-env option allows the user to define if the current environment
should be kept when running 'pct enter/exec'. pct will now always set
'--keep-env' or '--discard-env' when calling lxc-attach to anticipate
the upcoming change in default behavior.
