1) /var/log/lastlog exists and shows up as a 460GB (sparse I assume) file.
-rw-rw-r-- 1 root utmp 459G Aug 30 18:31 lastlog
2) There is an extra file in /etc/apt that should probably be cleaned up (sources.list.pre_fcopy). But there may be others around as well (haven't done an extensive audit).
-rw-r--r-- 1 root root 45 Aug 23 21:05 sources.list.pre_fcopy
3) Growpart and the package (cloud-guest-utils) to expand the root partition exist in FAI however nothing is doing the logic of calling it automatically. In bootstrap-vz, we used these
scripts. Does anyone have an idea how we should do this in FAI? The issue is that you need to pass in the root partition to expand (/dev/sda1 for example). But that can differ in different clouds and will also differ if you have a GPT disk and an EFI partition. We could do this with FAI variables but I don't know if someone has a better idea here.
