The Samba-Bugzilla – Bug 4105
FHS mode enhancements
Last modified: 2017-07-16 23:00:11 UTC
The FHS installation mode needs to a few enhancements to be really FHS-conforming. The following discussion is based on the fhs.patch that the Debian package has been carrying around for a while. The patch works well as far as the file-system layout is concerned but it causes some problems, so we'd rather see this work merged upstream before we diverge further.
Before I start, the current version of the fhs.patch can be seen at <http://svn.debian.org/wsvn/pkg-samba/trunk/patches/fhs.patch?op=file&rev=0&sc=0>.
Here are the issues:
(1) Installation of character handling files such as upcase.dat and lowcase.dat in /usr/lib/samba/. These files are architecture-independent, so they should be installed in /usr/share/samba. Our patch solves this by introducing a data_path() function that replaces lib_path() in certain cases.
(2) The "lock directory" contains a bunch of things, not all of which are locks. We have split this up into "lock dir" at /var/run/samba/, "cache dir" at "/var/cache/samba/", and "state dir" at "/var/lib/samba/".
The trick is that we have hardcoded the paths of the latter two, which annoys some users who would like to alter the paths (Debian bugs #247163, #249873). But the alternative would be adding more configuration options, which we don't want to do unilaterally. (There is a proposed patch available at Debian bug #268010.) So it would be nice if you take up that task.
[To see Debian bug #N, go to http://bugs.debian.org/N.]
(3) The "private dir" isn't really a problem by itself, but someone thought that it would be better to map its uses to the "state dir", since that is also read protected. So perhaps if you buy into the new directory options above, "private dir" can be phased out.
Thanks for considering.
this bug causes QEMU (http://fabrice.bellard.free.fr/qemu/) samba support to fail in Debian, as it launchs smbd not as root, but as the user running QEMU with the following configuration:
/usr/sbin/smbd -s /tmp/qemu-smb.$$/smb.conf
smb passwd file=/tmp/qemu-smb.3146/smbpasswd
security = share
smbd ignores "private dir" and tries to access secrets.tbd and messages.tbd from the hard coded path and fails.

"cache directory" and "state directory" are smb.conf parameters in Samba 3.4 and newer.

Marking as resolved on this basis.
The Debian FHS patches were all merged into master and are no longer carried in debian.
