SubjectRe: Initrd problem with 2.6 kernel
Date
> There is a chicken and egg problem with initrd on 2.6. When

{pts/1}% grep \"/sys\" *
do_mounts.c: sys_mkdir("/sys", 0700);
do_mounts.c: if (sys_mount("sysfs", "/sys", "sysfs", 0, NULL) < 0)
do_mounts.c: sys_umount("/sys", 0);
do_mounts.c: sys_rmdir("/sys");

or do you mean something different?
