I have version 2.2.20 (idepci downloaded) running OK (at runlevel 2).
I have version 2.4.18 (compiled myself under 2.2.20) running sort-of OK
(again runlevel 2).
One difference is that my self-configured/compiled version isn't establishing a network connection. Here are my thoughts as to why --
my thinking isn't good enough yet:
Something is different about the way these are booting up. Since
I see no error messages in /var/log/dmesg (or nothing I recognized as
an error message) and since the same /etc configuration files are
being used, I'm thinking the difference must come from tests of things
in the /proc system. So grep for "/proc" within the files found in
/etc/*.conf
/etc/init.d/*
The list appears below. Am I correct that my problem is probably
findable by considering this list? The only thing that jumps to
my eyes in it are the entries for the nfs ¯ I didn't compile support
for nfs into my 2.4.18 image
