Hello,

I'm trying to integrate my iBook into an existing amanda setup with
FreeBSD-CURRENT as server and client and another client running Fedora
Core 1. The iBook has Mac OS X 10.3 with latest patches and lots of fink
packages.

I built my own fink package for compiling amanda and everything went
astonishingly smoothly until I tried to do an actual dump. amcheck works
fine but sendsize of the amdump logs in /tmp/amanda:

sendsize: debug 1 pid 641 ruid 101 euid 101: start at Thu Oct 28 18:46:51 2004

The problem seems to be that runtar can't be executed. But its
permissions are set correctly:

-rwsr-x---  1 root  amanda  16976 10 Oct 22:36 /usr/local/fink/libexec/runtar

On further investigation I found that suid programs, su and sudo calls
on Mac OS X don't get their proper primary groups set. When doing an su
to amanda with primary group amanda, any file created will have
amanda:wheel as owner:

root@brithombar:/tmp # ls -la a
ls: a: No such file or directory
root@brithombar:/tmp # su - amanda -c "touch /tmp/a"
root@brithombar:/tmp # ls -la a
-rw-r--r--  1 amanda  wheel  0 28 Oct 19:21 a

Now I understand this is rather a Mac OS X problem than an amanda
problem but I wonder if anyone has come accros this before. Does the
fact that the filesystem is HFS+ have anything to do with it? Is there a
way to work around this for amanda so that is doesn't depend on runtar
being suid root and executable by group amanda?

Thanks in advance.
