/linuxrc query

[Amit D Chaudhary]

Hi,

I have a initrd working, a /linuxrc on it that runs and executes. My question 
for the commands after pivot_root which works like a charm, thanks to initrd.txt,

what does redirecting stdin\stdout\stderr to dev/console achieve? I thought 
since the root is now the "new" root, dev/console will be used automatically? 
Also, why chroot, why not call init directly?
#exec chroot . sbin/init 3 <dev/console >dev/console 2>&1

Since the above never returns, what follows in not freed. Does this mean I have 
around 4-6 mb of ram being used up unnecessarily? Any solution?

#umount /initrd
#blockdev --flushbufs /dev/ram0    # /dev/rd/0 if using devfs

Thanks and Regards
Amit
