Full Discussion: LibC.a usage in /usr/lib/boot/chrp.disk.proto
Operating Systems AIX LibC.a usage in /usr/lib/boot/chrp.disk.proto Post 302774339 by MichaelFelt on Friday 1st of March 2013 03:37:16 PM

The answer to your question, more to the point, is that libC.a, or any other file, is not needed unless the file is needed for the system boot.

So, until you add something that is used during the boot phase (e.g., a new device driver) it will not make any difference - because this file system gets mounted over by the disk version of / (root) (phase 2 of AIX boot, aka varyonvg rootvg phase).

To know more about the file layout, and the meaning of the content entries - read the manpage proto

excerpt:
Code:
Description

       The proto command creates a prototype file for a file system or part of
       a file system. The mkfs command uses the prototype file as input to
       construct a file system according to a predefined template. The
       prototype file consists of a recursive directory listing of every file
       on the file system, with its owner, group, and protection. It also
       contains the file from which the prototype file is to be initialized,
       formatted as described in the mkfs command.

home

HOME(8) 						      System Manager's Manual							   HOME(8)

NAME

       home, 40meg, 80meg, personalize, update, Disclabel - administration for local file systems

SYNOPSIS

       gnot/home
       gnot/personalize
       gnot/update

       magnum/home
       magnum/personalize
       magnum/update

       pc/40meg
       pc/80meg
       pc/personalize
       pc/update

       nextstation/home
       nextstation/update

DESCRIPTION

       These programs help maintain a file system on a local disk for a private machine.

       Home  partitions a disk, copies the appropriate kernel to the disk, and makes a new file system on the disk.  To do this, it overwrites the
       vendor-supplied software on the disk with a copy of Plan 9.  40meg, 80meg, and 100meg configure disks and make file systems  for  disks	of
       the appropriate size.

       Update copies the current kernel to the disk and updates files on the local file system.  It only updates those files put there by the home
       program.

       Personalize removes the contents of the /usr directory on the local disk and copies a minimal set of files for the user who runs  the  com-
       mand.

       The  file  /rc/bin/nextstation/Disclabel,  despite  its	name,  is not an rc(1) script.	It contains the second stage bootstrap program for
       Nextstations booting from local disk.  Before  booting  a  Plan	9  Nextstation	from  disk,  it  should  be  installed	in  the  partition
       /dev/hd1label; this is normally done by nexstation/home.

FILES

       /lib/proto/portproto
	      Mkfs prototype files for magnum/home, magnum/update, gnot/home, and gnot/update.

       /lib/proto/386proto
	      Mkfs prototype files for pc/40meg, pc/80meg, and pc/update.

       /rc/bin/gnot/*
