doing "ps ax" get such msg for kernel-2.4.9:
That is the same for kernel-2.4.12.Sometimes it is shown as it should be.
Is this a bug of kernel? It seems to be..
PID TTY STAT TIME COMMAND
1 ? S 0:06 init [

It's because init doesn't have enough space in argv[] to change it's
process title. There are a number of causes for this, one indirect
one is pressing 'enter' at the 'LILO boot: ' prompt.

Perhaps a way around this frequent problem is to make execve() always
reserve a certain minimum amount of space in argv[] even if it is not
filled in with anything. Then instead a "brick wall" being set at
the end of the space originally used, it can be set at max(space used,
minimum reserved). This is still userland space, right? What would
be a reasonable figure for minimum reserved? Or does ld-linux go
grabbing space right after the end of argv[]?
