ash ulimit

[Thomas Tornblom]

Your problem is that the commands you use to change the value starts a 
new shell, changes the value in the new shell, then that shell exits. 
The "ulimit" command only affects the current and child shells, not the 
parents.

If you want to change the value permanent you can add the following line 
to /etc/profile or ~/.profile:
---
ulimit -c
---

Example:
---
root at ROOter-Uppsala:~# ulimit -c
0

root at ROOter-Uppsala:~# busybox sh -c 'ulimit -c 1024'

!! This starts a new shell, changes the ulimit value in that shell, then 
it exits and you are back with your first shell

root at ROOter-Uppsala:~# ulimit -c
0

!! no change

root at ROOter-Uppsala:~# ulimit -c 1024

!! "ulimit" is a shell built in command, so this changes the value in
!! the current shell

root at ROOter-Uppsala:~# ulimit -c
1024
