 How to change busybox [with a self compiled version] |
|
I'm trying to replace inbuilt busybox with my own (personalized) busybox to suit my features by directly editing the .sfs file
When i replace the /bin/busybox ( in the sfs ) the switch_root in initrd.gz is unable to switch the root to the sfs ( could not find /sbin/init Kernel panic ... )
Earlier was able to simply add/remove whatever files i required after using unsquashfs, and finally using mksquashfs. Without the system to break.
This doesn't work with busybox, rather doing this gives the error mentioned ...
PLUS, i also tried replacing busybox in initrd.gz ( and in /init tried copying the busybox from initrd.gz to /pup_new/bin ) but this didn't even let the initrd.gz boot, giving the "init not found .. kernel panic" for the initrd.gz itself. I.e. the message for "Loading necessary modules ..." never appeared.
Also tried it with a defconfig busybox, in case my configs were bad, but still didn't work

Hm...
Replacing busybox on any distro sounds like very major surgery.
Perhaps replace only the apps you need? I replaced the busybox "less" with the real one (less-444) and never had a problem.
Good luck.

For the initrd : compile statically :
For other watch out for the No Machine Whatever option : this disabled ash in the shell section in my cases (1.17,1.1 .
You need ash enabled , because roundabout a half dozen important scripts like /etc/rc.d/rc.sysinit use #!/bin/ash as the interpreter .
Busybox is very important providing replacements for lots of elementary binaries like login,su,nice,kill,tr, ...
For a dotconfig:
