Poking around in the code again and see that clamscan use P_tmpdir to
find the default temporary directory and at least in Solaris that is
defined in /usr/include/stdio.h as /var/tmp/. That trailing slash shows
up as /var/tmp//clam..... as I noted in my earlier truss output so the
code seems not to expect it and adds another when it creates the temp
dir as seen here:
mkdir("/var/tmp//clamav-f90088fbc83891f9e230bfcfab5b3884...
There are other interesting things that happen if you run clamscan as an
unprivileged user vs running it as root. If you're not root it creates a
lot of tmp files (in /var/tmp//clamav..... here) that correlate to the
database files and .dbLock found in the defined database directory. This
means things would run faster using /tmp instead of /var/tmp as /tmp is
RAM in Solaris. It's also not real good about cleaning up old session
files. Frinstance:
$ ls -la /var/tmp/clamav*
