From: Orena Radrax on 21 Jul 2010 12:50 Hi, I'm desperately trying to migrate a Mac OS X installer to a smaller system. The current installer is very basic: it is a Mac OS X system that boots on an external drive and run a script that creates 3 partitions on the local disk, then restore DMGs on them, and finally set the boot flag to the correct partition. Technically, it is hdiutil (or diskutil) to create the partitions, asr to restore DGMs, and bless to take care of the boot. On of the DMGs is also a full Mac OS X system. The result is a very heavy installer (even if we removed most of the useless stuffs). I can build a very light FreeBSD system (using m0n0wall or FreeNAS projects) but I will need HFS+ support. I successfully compiled gpt fdisk to create partitions on a GPT drive. Now I have to create the filesystem and manage the DMGs. I saw that hfsutils can handle them, or they can be converted to IMGs. But I am not able to find a suitable tool to create an HFS+ filesystem (even non journaled). GEOM_APPLE has been removed. The hfs port is ultra deprecated. Linux has a lot of working tools to handle HFS+ (read and write on non-journaled). There are also source codes from Apple. But I can't find anything for FreeBSD. Does anyone have a clue?

I believe GEOM_APPLE was replaced with GEOM_APM (Apple Partition Map) and GEOM_GPT. However I have never been able to get HFS+ support to work at all in FreeBSD. -- Caveat utilitor, indi

Gdisk and sgdisk work fine on Linux. I was able to get the content of the dmg by first converting it to img (I don't know why I can't mount the dmg directly). So far so good until I realize: - I will have troubles with the boot (maybe rEFIt can do the trick?) - The Linux HFS+ support doesn't manage resource and data forks. That's a bad news when you want to copy a Snow Leopard system. Linux can't read the compressed files (just like Leopard can't). I think my best bet is PureDarwin. HFS+ is definitely for Mac only :/

HFS+ is definitely for Mac only :/ Interesting. I notice the PureDarwin site has been without an update since January, which is a bit sad. Why are you building your own OS X installer? -- Caveat utilitor, indi |
