Ha, I think I got it.
LS_COLORS is included by default in env_keep.
If you don't set (or just append to) env_keep, LS_COLORS will be passed
on, irrespective of -i and/or env_reset. If you overwrite env_keep (by
assigning to it), LS_COLORS will be wiped from the environment.
Can you reproduce that?
And now that I know what to look for, I found it in the docs, in
sudoers(5), the description of env_reset:
| If set, sudo will reset the environment to only contain the LOGNAME,
| MAIL, SHELL, USER, USERNAME and the SUDO_* variables. Any variables in
| the caller's environment that match the env_keep and env_check lists
| are then added. The default contents of the env_keep and env_check
| lists are displayed when sudo is run by root with the -V option. If
| the secure_path option is set, its value will be used for the PATH
| environment variable. This flag is on by default.
Also note that that's not even true, sudo -V displays the current (from
/etc/sudoers) values of env_*, not the default (compiled in) ones.
Do you agree this is a documentation issue then?
cheers,
Jan
