I am building a system with a kernel with the loop-aes loop module and patched util-linux, but at install time I am getting an error with this in the backtrace of anaconda _isys.lochangefd(loop, targ) SystemError: (22, 'Invalid argument') After googling a bit, I found out that this might be due to a kernel patch that used to be applied to kernels 2.4.x for anaconda to work. This is already in the vanilla 2.6.x kernel, I think since 2.6.4 or so, but the sources in loop-aes do not include such changes. Does anyone happen to know what changes are they, or where can I find a patched loop-aes that will work with anaconda, or else how can I create an anaconda install cds that will use one kernel and util-linux for boot disks, but install others? (i.e. add kernel-2.6.9_loop_aes and util-linux-2.12q_loop_AES alternative rpm files)
