Hi Chris,

Your script works like a charm. Thanks! There is one thing though... If
I run the script as a plain user with the repository in
/home/patrick/rawhide, it always fails at the mkisofs stage. If I run it
as root it works as advertised. The command I use is:
cd /home/patrick/
./FedoraSync.sh -live -del -paranoid -iso i386

The error message I get as a plain user is:
Size of boot image is 4 sectors -> No emulation
mkisofs: Permission denied. Error opening boot image file
'./isolinux/isolinux.bin' for update.

In the current rawhide tree isolinux.bin is 444 and mkisofs needs 644 to
do it's thing successfully.

Is changing isolinux.bin from 444 to 644 something that needs to be done
in the rawhide tree or do I just work around this "feature" by changing
isolinux.bin from 444 to 644 in the script just before the mkisofs
command is issued and afterwards change it back?

Thanks,
Patrick
