[Pkg-shadow-devel] su vs. utmp

[jidanni at jidanni.org]

Interesting. On tty1 I "su -" from jidanni to root, and on tty2 from
root to jidanni,
$ pstree -au
  |-login --
  |   `-bash
  |       `-su,jidanni - jidanni
  |           `-bash
  |-login --
  |   `-bash,jidanni
  |       `-su,root -
  |           `-bash
  |               `-pstree -ua
But who(1), w(1) don't divulge any of that. OK, no big deal.
