I looked at vsdbutil -c in Bwana, but didn't really follow what I read; can you explain why my answer differs from yours?

> Anyway, once we measure all the hidden stuff too (seems i have a fat 4 gig /var/vm/sleepimage file to accommodate), i think trying this on a 8 gig disk would be way too tight.

In an extraneous e-mail from Ted Landau he mentioned running Snow Leopard on either an 8Gb or 16Gb flash drive, so I knew it could be done on an 8, but I was close to tearing my hair out, what with not being able to get the installation small enough, until I remembered to disable safe sleep and trash /var/vm/sleepimage.

My installation is (quite obviously) totally stripped down, but I can carry my deuced Mac(hina) in my shirt pocket, with everything I really need, if I choose to do so.

(Your response to dk about partitioning is appreciated; I didn't care to get into that issue yet again.)

Formatting the drive wasn't the time consumer. I don't recall the time used but choosing the one partition and formatting GUID was only a matter of minutes.

The actual system install took all the time and it was done having booted from the Snow Leopard disk.

That is something that I could do as I have a clone on a FW hard drive. The only difference is that I use Super Duper.

And that's a worrisome issue. It makes me wonder if I should just bite the bullet and get a couple of those very small HDs that are firewire powered.

Perhaps so. It's just that I'm always troubled when something very oddball happens and it is there for me to see. I start wondering "If that's what I can see, what has happened that I can't see?"

Ah, right you are... it appears in the first comment here:
...where Ted replies to himself, to update the article. I had forgotten about that sleepimage tidbit. (wonder if i should bother deleting mine or not). I notice that cnet has wrecked the urls in our posts there too. Here is mine again:
That one uses Pacifist in a sneaky way, to install Leopard on a 2 gig flash drive!!!

[edit: i just did a regular (albeit minimal) install off the SL DVD, as opposed to either cloning or tricks with Pacifist.]

It's just a way of officially unchecking the "Ignore ownerships on this volume" checkbox. [i mostly threw that in for Virtual1, since it was just discussed in another thread (upstairs).] You'll see it mentioned in that 2nd link as well.

I work with a lot of drives (as if the vs db above didn't give THAT away!) and so far I've seen about 8 volumes revert back to the default drive icon.

I've found that I get info on them, and they show their correct icon in the info window. I select it, copy, and then immediately paste, and it's fixed. and does not break again. I presume it's an issue with leopard vs sl icon storage.
