Thanks for the idea of recompiling, Nathan.
I wish I had no problems too. :(
Though you advised to recompile the kernel, I thought of recompiling
sendmail, ftp(d), telnet(d) and some other programs which are compiled
with something like '-DINET6' option. But I am really a newbie and I do
not know whether I break anything just removing '-DINET6' from several
/usr/src/.../Makefile's and running 'make world' then.
I would like to have the same system as you have (4.5-STABLE, that is).
Yesterday I run
# cvsup -h cvsup2.freebsd.org stable-supfile
where stable-supfile contained the following:
==================================================
*default host=cvsup1.FreeBSD.org
*default base=/usr
*default prefix=/usr
*default release=cvs tag=RELENG_4
*default delete use-rel-suffix
*default compress
src-all
==================================================
Did I do the right thing? You wrote about '4.5-stable from releng_4_5'
and I am confused now: should I use
*default release=cvs tag=RELENG_4_5
instead of
*default release=cvs tag=RELENG_4
?
I will have holidays till May 13, but then I hope I'll be able
to *properly* cvsup my sources and recompile them (probably commenting
out '-DINET6' strings in several Makefile's).
