[Samba] Re: chdir (/root/tmp) failed - but why is it trying?

Well - I've found out the reason. On the system in question
(Mandriva2007) TMPDIR is set to ~/tmp on login, and I was starting Samba
from the command line (rather than as a service at boot time). When I
unset TMPDIR in the startup script all is OK.

Not sure why Samba decides to chdir to TMPDIR (or rather, to the result
from tmpdir() in lib/util.c) when being queried for IPC$ (?), which
seems to be what is happening ("real" connexions worked OK - it was just
the behind-the-scenes one that failed). But letting this default to
/tmp lets things roll OK.
