Description:

/etc/environment is sourced, when you login using text console, desktop manager or ssh, but not sourced by the command `su -` (with hyphen).
This is because pam_env module not mentioned in /etc/pam.d/su-l

I expect that issuing `su -` will have the same effect as logging in using other methods.

Please append extra line to the default config file /etc/pam.d/su-l :

session required pam_env.so

Additional info:
* package version(s)
util-linux 2.28-1

Steps to reproduce:

- put the following in /etc/environment :

AAABBB=cccddd

- login using text console
- ensure the variable is set:

$ echo $AAABBB
cccddd

- login using su - :

$ su -
Password:
#

- ensure the variable is not set:

# echo $AAABBB

#
