When installing debian-edu 7.1 (wheezy), if I let the installer automatically partition my hard drive, it will work well.
However, when I chose to manually partition myself, it would make the permission of /skole/backup, sometimes the whole /skole become very strange:
d-w-r-xr-T 2 root root 4096 Mar 19 15:16 backup
If it happened in /skole it would be impossible to log into X desktop since it would not be able to write some files.
I have tried several times. Automatically partitioning was *always* okay. Manually partitioning would *always* make /skole/backup folders inaccessible, *mostly* /skole inaccessible, but the last time I tried /skole was correct.
