On the topic of numeric/shorthand/binary error messages in the kernel, I
did a few measurements. Here they are:
grepping out all strings (probably only one-line strings, are there
multi-line error messages) and counting characters:
% for a in `cat /tmp/chfiles.kernel.list` ; do
egrep '"(.|[$^])+"' $a
done > /tmp/strings.in.kernel
% cut -d\" -f2 /tmp/strings.in.kernel | wc -c
1163971
In other words, the strings in the kernel take up about a megabyte. For
my configuration, I did:
$ strings vmlinux | grep '........' | wc -c
81902
(The grep is for cutting away characters that just happen to be
printable) So that's 80K of a running kernel, or about 10% of the size
"wasted" on strings.
Presumably this could make a difference in systems short on RAM, like in
an embedded environment? It doesn't sound too bloated for general
server use, though - in particular, since the "bloat" would have to
reside elsewhere (OK, so it could be swapped out more easily)
