Hi,
I am building a custom initrd for booting a Fedora 3 based system.
In general all is working fine, except that when I try an umount the initrd
after boot has suceeded the system hangs with no error messages.
I have created a cpio based initrd using busybox. A simplified version
of the "init" script is attched. This finishes with running /bin/sh on the
hard disk mounted file system. If I try and run "umount /initrd1" the system
hangs.
The system is booted using PXE based network boot using pxelinux 3.0.9.
I am using busybox-1.00.
The kernel is Fedora3's version 2.6.11-1.35_FC3smp.
Any Ideas ??
