[systemd-devel] lastlog and friends

[Karel Zak]

 systemd TODO:

    - Replace utmp, wtmp, btmp, and lastlog completely with journal


 Can someone elaborate and provide more details, ideas, .. ?


 The current lastlog is sparse file and it's difficult to use for backup 
 programs or integrity checkers, etc. So requests from users/customers
 are pretty common.
 
 The idea (from someone from RH) is to have very simple and tiny
 library that provides unified API for different backends (classic
 lastlog, systemd journal, etc.) to keep applications portable.
 Something like:

 Frankly, I'd like to see something more than only lastlog, but also
 utmp, wtmp support.
 
 Note that I'm not involved in the project, but as login(1), last(1),
 ...  maintainer I'd like to see a public discussion about this topic.


 Maybe all we need for things like lastlog and wtmp is journald and then 
 a few #ifdef in applications like login(1), who(1) or PAM. Maybe it
 would be better than add an extra abstraction layer (by any library).
 Not sure, too many question :-)
