I have experienced two major problems with the new libc.so.4.2. (Note that
I started my Linux with SLS .98p5)
1) The new library has an improved "gethostbyname". A new file
/usr/etc/inet/host.conf is used to set options. If this file is missing,
a file containing a single line
order bind
is assumed. This means that ONLY DNS is used to resolve hostnames. Your
/usr/etc/inet/hosts is never consulted! As I don't have the named
running, I had to create a file /usr/etc/inet/host.conf containing
the line
order hosts
Actually, you can have
order hosts nis bind
or any other combination. I did not try to find out about the other
keywords that can be used in host.conf from the source. Perharps
whoever wrote the new version can post a little doc.
2) sed doesn't work any more. I have recompiled it using FSF sed-1.13.tar.Z.
Strange enough, although I removed the sed-local regex.o getop.o and
getopt1.o (thus using the functions in libc.so.4.2) and compiled with
-O2, my new sed is about twice as large as the old one. Was it not
FSF sed-1.13 in the SLS distribution?
Hope that helps.
