[Idea] User-defined post-install modifications

[burgerga]

Whenever I create an LXC/VM I would like to add some small tweaks to its ~/.bashrc, e.g.,

set -o vi
alias vim=vim.tiny
export EDITOR=vim

or create certain files (e.g., authorizedkeys)

It could be completely out-of-scope for this project, but it would be nice if there would be a "hook" at the end of the script to do these modifications based on, for example, a config file on the proxmox host
