Does anyone knows about utmp and wtmp handling?

[Sebastien Bacher]

Hey,

That's a call for help,feedback,comment on lightdm bug #870297 [1]: 
"Lightdm logins not being logged in wtmp"

 From the comments and feedback that seems like an issue that should be 
fixed in the lts, there is a merge request proposed to fix it on:
https://code.launchpad.net/~lotheac/lightdm/utmpx/+merge/107739

The lightdm project has been trying to avoid adding code "just because 
it's this way for 25 years" but trying to understand if things still 
make sense on a modern linux distribution rather and that's where we 
need your help.

Does anyone knows if:
- utmp and wtmp support is still important?
- if those are "speced" or described in a reference document somewhere?
- if the login manager is the right place to record those entries?

Review of the previous listed merge request from people who know about 
the topic would be welcome as well

Thanks,
Sebastien Bacher
