UDF instead of FAT on USB storage

| No Comments
I just stumbled across http://tanguy.ortolo.eu/blog/article93/usb-udf. This makes a good argument for using the UDF file system on portable drives instead of FAT. I reckon I'll be doing that next time I have to format some USB storage.

blessing Linux boots on iMacs

| No Comments
I've just worked out how to get my iMacs to boot into linux by default. Previously I've blogged about my efforts to install Debian on an iMac and a macbook air. The arch linux people have documented how to bless you're linux boot loader. They say you need to boot into Mac OSX, and then mount the efi volume. Over on themacadmin.com they describe how to mount the efi volume.

So I ended up doing the following commands:
diskutil list # Which showed /dev/disk0s1 is the efi volume
sudo mkdir /Volumes/efi
sudo mount -t msdos /dev/disk0s1 /Volumes/efi
sudo bless --folder=/Volumes/efi --file=/Volumes/efi/EFI/boot/bootx64.efi

I'm going to have to do this on all my Debian running macs now!
