[PATCH] net/samba4: relocate Sysvol to persist between reboots & move variable data out of /usr/pkg/etc/...
with the introduction of FFS ACLs Samba can be used as windows domain
controller (DC). The DC needs a directory to persist its policies and
scripts - the so called Sysvol.
The creation of the Sysvol typically takes place during the domain
provisioning with samba-tool. At the moment, the default Samba4 from
pkgsrc is configured to put Sysvol below /var/run/sysvol. Unfortunately,
there is a critical issue with this location: Everything inside /var/run
gets purged as part of the systems startup sequence. So this means
losing all your policies, ultimately a corruption of the domain
controller state at the next reboot.
Therefore, Sysvol needs to be relocated to a persistent place.
I checked how this is implemented elsewhere:
* On Linux systems Sysvol is typically located at /var/lib/samba/sysvol
* On FreeBSD the location is /var/db/samba4/sysvol
As /var/lib is not mentioned in HIER(7) at all, I guess this is Linux
specific. Therefore I would propose the FreeBSD-way and put it below
/var/db/samba4/sysvol. In addition to that I think it would be a good
idea to relocate the variable Samba data (databases, caches) currently
located at /usr/pkg/etc/samba/private) as well. My proposal for the
target is /var/db/samba4/private.
Attached is a patch which applies to pkgsrc-current. I did perform the
usual tests (removing all previous configuration and databases,
provisioning a new domain, joining a Windows client to the domain) - no
issues so far.
What do you think?
