[LITMUS^RT] litmus-dev Digest, Vol 32, Issue 1

[gokul vasan]

Hello Glen,

thanks for the reply, but my question is little more primitive, I am not
able to bring up the userspace; in other words I dont have a
early-userspace or initramfs or initrd to get my RFS mounted, causing me
trouble of

"VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6"

which i understand is because of i dont have Initramfs.

Now my question is should i create my own RFS/ initramfs ? which holds all
my libraries including liblitmus or is there a short-cut for this?

please advice me, as i am going to create my own Initramfs using Busybox
which is time consuming.

Thanks and Regards,
Gokul Vasan
