The thing you need to do is to manually set the kHasCustomIcon flag in
the corresponding FolderInfo structure. The only problem is that when
the folder (ex. /Volumes/Test) is not mounted, all finder info will be
stored using HFS+ extended attributes (looks like folders themselves
do not have resource forks). And when a volume is being mounted on the
folder, all extended info will be stored in a resource file (prefixed
with "._") and all extended info set before mount will be discarded.
So, the solution is the following:
1. Create folder for mounting (ex. /Volumes/Test)
2. Mount your FS with -onoping_diskarb flag. The finder will not show
the volume.
3. Set the kHasCustomIcon flag on your folder (see listing below).
4. Notify DiskArbitration about newly mounted VFS.
An example routine for setting kHasCustomIcon property from C code is
shown below. The routine for "pinging" DiskArbitration
(ping_diskarb()) is taken from macfuse sources. The original one
cannot be used because you need to set kHasCustomIcon just after the
VFS mounts and before it appears in Finder.
