Tool for blessing HFS+ filesystems required
Hello!
I had a closer look at the bootloader installation on PowerMacs today and realized
that so far we never blessed the bootloader partition on hard disk which is why the
installed Debian system never showed up as a selectable icon in the OpenFirmware
boot menu. We merely hard-wired the boot path for GRUB in NVRAM.
At the same time, hfsprogs - the original HFS filesystem utilities by Apple - can
no longer create HFS filesystem after I updated it to version 543 but only HFS+
filesystems.
While NewWorld PowerMacs can actually boot from HFS+ partitions, we're missing a
tool in Debian to bless folders on HFS+ partitions. The hattrib utility from the
hfsutils package which can bless folders doesn't work with HFS+ filesystems and
the hfsplus package doesn't have any hattrib utility (yet).
In order to solve this issue, we have a couple of options:
- Use HFS instead of HFS+ and use the old hformat utility in grub-installer
- Use HFS+ with hfsprogs and port Apple's bless utility to Linux [1]
- Use HFS+ with hfsprogs and write a blessing tool based on libisofs [2]
I'm not sure whether the libisofs approach would work, but in any case the installation
CDs actually use HFS+ and have a blessed system folder which is displayed by the menu
in OpenFirmware.
Other suggestions?
