Hi,

After a marathon session spread over 2 days, I have managed to set up a 
new FreeBSD-7.2 installation with all ports (762) up to date. From the 
gleanings of this conversation and some reading I did myself, I have 
compiled a small document for what-to-do-after-installation. I would 
dearly appreciate your comments on the document, and would be extremely 
glad if my document could be of any help to somebody else too.

Please note that portupgrade works much better on my system than 
portmaster. So the following document assumes/recommends using portupgrade.

Here it is.

==============================================
Part-1)    Immediately after a fresh FreeBSD-7.2#RELEASE install :

I assume you will at some stage or the other install a linux port, eg 
acroread8 or acroread9, linux-ymessenger, etc. Incidentally, unless you 
have specific needs, prefer acroread8 over acroread9.

All following steps are to be executed as root.

a)    Make sure /etc/rc.conf has at least the following 5 lines.
dbus_enable="YES"
hald_enable="YES"
polkitd_enable="YES"
gnome_enable="YES"
linux_enable="YES"

b)    Make sure /boot/loader.conf has at least the following 3 lines.
kern.maxdsiz="734003200"
linprocfs_load="YES"
linsysfs_load="YES"

c)    Make sure /etc/fstab has at least the following 3 lines.
proc        /proc                                   procfs        
rw        0        0
linproc     /usr/compat/linux/proc        linprocfs    rw        0        0
linsys       /usr/compat/linux/sys          linsysfs      rw        0   
     0

d)    Upgrage from python25 to python26 along with all dependent ports 
as follows :

rm -rf /usr/ports 2>/dev/null
mkdir -p /usr/ports/distfiles
portsnap fetch extract
cd  /usr/ports/ports-mgmt/portupgrade
make deinstall  2>/dev/null
make install clean
portupgrade -C -r -o  lang/python26  lang/python25
portupgrade -rfx python26 python26
pkgdb -F

Before doing anything further, reboot. Immediately after reboot, execute 
Part-2.


Part-2) Steps to be followed whenever a significant number new 
ports/patches are available and you need to ensure your ports as well as 
your ports directory are up to date :

thisdate=`date "+%Y-%m-%n"`
rm  /root/portupgrade-${thisdate}.log 2>/dev/null
portsnap fetch update
portupgrade -ace -uRl  /root/portupgrade-${thisdate}.log
pkgdb -F

Note : If you plan to install any linux ports, you should have said yes 
to 'Linux binary compatibility' at the time you installed FreeBSD. If 
you didn't, the very first port you need to build is 
emulators/linux_base-fc4
==============================================


I look forward to your comments and suggestions.
