Enabling autofs and autofs-ldap on tjener results in /skole being hidden by the autofs mountpoint.
TL;DR; Please revert your change that hard-codes tjener in debian-edu.git (42b28ab02). Here is why...
10:00 < h01ger> sunweaver: also a comment on Natureshadow's (yet unuploaded) commit in src:debian-edu.git would be appreciated. i dont like the hardcoding of tjener in it, plus its probably not needed(?), at least according to wolfgang, though Natureshadow somewhat disagrees
10:01 < h01ger> #876376 is the relevant bug10:02 -zwiebelbot:#debian-edu- Debian#876376: debian-edu: autofs daemon on combined server breaks homes and NFS - https://bugs.debian.org/876376 10:12 < sunweaver> h01ger: I just chatted with jonas, d-e-a-spacefun will be the first uniform package consumer.
10:12 < sunweaver> see the Debian Design BoF at dc17 10:12 < sunweaver> so, I'm happy. 10:14 < sunweaver> oh oh the commit is nasty. 10:14 * sunweaver thinks about a more generic solution while hoovering... 10:15 < sunweaver> Natureshadow: ^^^ 10:16 < sunweaver> what is bad about it... is the original cause... 10:17 < sunweaver> physical homes are in /home on TJENER. 10:17 < sunweaver> symlinked to /srv/nfs4 10:17 < sunweaver> those get exported by NFSv4. 10:17 < sunweaver> and /skole should only be managed by autofs.10:17 < sunweaver> if autofs realizes that a mount point would end up on the same host, it normally uses bind mounts. 10:18 < sunweaver> so the question is, why does autofs f*** up things on NatureShadow's setup in the first place. 10:18 < sunweaver> The patch IMHO is wrong and shadowing some other, maybe even more severe issue.

This is conceptually wrong. 10:44 < sunweaver> Only folder under /skole that may contain physical files is the /skole/backup dir.
10:44 < sunweaver> the others are mere mount points10:45 -!- olinuxx <~capturixe@2a01:cb11:416:ed00:49d0:dd6e:15ac:ab4d> has quit (Ping timeout: 480 seconds) 10:45 < sunweaver> we put files into /srv/files and symlink those folders to /srv/nfs4. Then we export /srv/nfs4 and subfolders via NFSv4 and extra automount rules to LDAP for these extra mount targets. Under /skole/ we had extra empty dirs as mount points.
10:45 < sunweaver> e.g. /skole/transfer 10:45 < sunweaver> /skole/tjener/transfer, actually.10:46 < sunweaver> /skole/tjener/home1 (for teachers), /skole/tjener/group0 for student+teacher groups and /skole/tjener/group1 for teachers-only groups. 10:46 < sunweaver> so, please undo that commit and let's see what's causing the problem on your system. I assume, you used /skole as physical file storage.
