10.4.11 installer disk with EFI patch included.
First of all, I like to thanks Netkas for his job on the EFI patch, amazing stuff!!!.
As the title says, Im working on a 10.4.11 DVD and Im trying to include the EFI patches as an installer option. I successfully added the MBR ones without problems (a shell script does all the job). The trouble comes with the GUID ones, when trying to dd boot0 to dev/diskX. Aparently all partitions on the disk needs to be unmounted otherwise I get 'resource busy' message.
I would need some sort of command that give me a numerical output according to how many partitions are on the disk. Then I could do a variable out of it and use it to unmount the partitions.... or a way to unmount all partitions at once (I dont know if this is possible)
If someone has an Idea about this please share it here....
