technical question on booting

[Stefan Jeglinski]

Please correct any and all misconceptions below :-)

The Linux kernel, at some point in the boot, runs init, which parses 
the inittab file, which on a RedHat distribution, runs rc.sysinit as 
a first step.

Now, rc.sysinit is a sh script. Could rc.sysinit in principal be a 
bash script instead? Regardless of this, does sh (or bash 
alternatively if rc.sysinit was a bash script) already have to have 
been run by the kernel? If so, where and how is this specified or 
take place?
