hello all

i want to edit rc file before rebuild kernel that can't find rc file in ~/root/etc dir.

i don't like to excute "ifconfig" or "inetd" command every time under the uclinux.

can i add a rc file in ~/root/etc dir?

on uclinux : ~/bin/login

i don't know uclibic login's account and "password".

how to know my account and password ?

because i don't login to use my uclinux os every time . so , i want to creat it..

how to creat a account on uclinux os?

thanks in advance !

There are many ways to add init tasks.

you can add simple init command into etc/inittab, just like the lo init.

you can add a line in inittab to run etc/rc .

you can uncomment the line contains /etc/init.d/rcS in inittab .

then ~/rootfs/etc/init.d/rcS will be executed during linux init.

the default rcS will run each Sxxxxxx task.

the account and passwd file are etc/passwd and etc/shadow .

the simple inittab from ~/download, does not use login, it call /bin/sh directly.

Hi hippo

I have edit "inittab" file in ~/rootfs/etc and recompile kernel .

But not update the initramfs....

compile kernel info:

perl -I/home/jay/linux-2.6.16.1/arch/nios2nommu/scripts /home/jay/linux-2.6.16.1/arch/nios2nommu/scripts/gen_nios2_system.h.pl cpu_0 sdram_0 cfi_flash_0 < nios_0.ptf > include/nios2_system.h.tmp; if [ -r include/nios2_system.h ] && cmp -s include/nios2_system.h include/nios2_system.h.tmp; then rm -f include/nios2_system.h.tmp; else echo &#39; UPD include/nios2_system.h&#39;; mv -f include/nios2_system.h.tmp include/nios2_system.h; fi

CHK include/linux/version.h

CHK include/linux/compile.h

CHK usr/initramfs_list

Kernel: arch/nios2nommu/boot/zImage is ready

I don&#39;t see the "GPIO" and "GZIP" in compile messages and not find "initramfs_list" file in ~/rootfs/usr/ dir.

Why not to update the kernel?........... http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif
