In my system I set the umask for the user root to 0077 and for the non-root users to 0027 (via /etc/profile). This is working for the normal terminal logins. But if I login as root and change user with su command like this:

```
su user
umask
0077

```

I get the `0077` umask instead of `0027`. Is this normal behavior? how can I configure my umask `0027` setting for the `su` command to `0027`?
My default shell for the non-root users is the dash not the bash
