Re: [Devil-Linux-discuss] Making bootcd.iso

[Bradlee L. <bra...@gm...>]

Thanks for the reply. I actually did download the ifssystem and get it to
compile and everything, but I kept getting an error about
register_chrdev_Rsmp_00133218. The module would compile and almost work
except for the error. I don't think it is specific to DL, but may just be
the module itself that has a problem.

Again, thanks for the help.
