[Bug 1612028] Re: "sudo -i" does not read .profile when root uses bash

[Karl-Philipp Richter]

** Description changed:

  According to `man sudo` `sudo -i` is supposed to read `.profile`, but
  apparently it doesn't since adding `alias ll='ls -la'` to the end of
  `/root/.profile` causes `ll` to fail with `ll: command not found`, but
  the alias should be available if `.profile` was read. `root` uses
  `/bin/bash` according to `/etc/passwd`.
+ 
+ Now, I got it. /root/.profile is only sourced at the first sudo -i after
+ reboot (or maybe display manager (re-)login), not at every following
+ sudo -i - at least in gnome-terminal. If sudo -i is run once when
+ /root/.bash_profile is present it is sourced (and /root/.profile skipped
+ as expected) and if it /root/.bash_profile is removed every following
+ invokation of sudo -i causes /root/.profile to be sourced. That not
+ right, right?

Title:
  "sudo -i" does not read .profile when root uses bash

Status in sudo package in Ubuntu:
  New

Bug description:
  According to `man sudo` `sudo -i` is supposed to read `.profile`, but
  apparently it doesn't since adding `alias ll='ls -la'` to the end of
  `/root/.profile` causes `ll` to fail with `ll: command not found`, but
  the alias should be available if `.profile` was read. `root` uses
  `/bin/bash` according to `/etc/passwd`.

  Now, I got it. /root/.profile is only sourced at the first sudo -i

  following invokation of sudo -i causes /root/.profile to be sourced.
  That not right, right?
