When I sudo to root vi mode is turned off, so that I need to either run set -o vi or change root's profile to use vi mode. I don't want to change the profile as this will impact other engineers and I don't want to have to type set -o vi every time I sudo. I read man sudo and tried sudo -i and sudo -sE, but neither of these preserved $SHELLOPTS where vi mode is set.
I did find that setting env_keep += SHELLOPTS in /etc/sudoers fixed the issue, but this file is being maintained by a config mgmt system and I don't want to make such a global change just because I prefer vi as my command line editor. So, ultimately is there a way I can set this when sudoing that will not require making changes to shared and/or managed config files?
[user@host:~]$ echo $SHELLOPTS

[user@host:~]$ sudo -i
[root@host:~]# echo $SHELLOPTS

[user@host:~]$ sudo -sE
