Looks like bad logic to me. Here's where the call is coming from (mind
you I'm referencing pkg_install from CURRENT's sources):
.../usr.sbin/pkg_install/info/perform.c:142 if
(unpack(fname, "'+*'")) {
.../usr.sbin/pkg_install/lib/file.c:354 if
(vsystem("/usr/bin/tar -xp %s -f '%s' %s", comp, pkg, flist ? flist :
"")) {
Looking at the if-statement, it appears that the logic for the package
finding is in fact sort of convoluted -- we should first check and see
whether or not the package is installed, THEN if it's not installed we
find the tarball (either from a local filesystem or a remote host),
extract it, and grab the appropriate info.
Does that sound like what should happen?
Thanks,
