I don't really care where it is done, in glibc or in the kernel - but let's
honor this convention and not needlessly break code.

If you are PID 1, make sure that you handle SIGCHLDs etcetera from daemons.
Check the source of init, I suspect it does something which tells the kernel
'I am your init'.

some documentation can be found on
ftp://ftp.linux.org.uk/pub/linux/sct/fs/raw-io/raw-19990728.tar.gz
AFAIK you don't need any patches anymore if you run 2.4 or a recent 2.3.

does fsck run on this fs find any errors?

Try using 2.2.18 - lots of work has been done to get the eepro100 working
properly.

Hi,
I'm fighting my PPro200 desktop to get it to support the USB pci card I just
bought. At first the entire computer became instable but choosing CMD640
chipset support solved that problem.
But now I find that
ernel at least does some of the work. Does anybody know if these socket
options work as they should under Linux, and if so, which versions?
I might even whip up a better entry for the manpage if given enough data.

Or configure your host to do MSS Clamping. I have a similar situation over
here and no problems.
