su: not running setuid

Switch .. switch now and you will love it.

i just spent 3 days trying to get unixODBC working on
linux... . I got
it to work in about 10 min on Freebsd. Freebsd rules... its
a slight bit
different but it rules.

You will never go back once you port something.....

And you can say that with FreeBSD you get a stable system as
Debian
GNU/Linux is _and_ you get a source based system as Gentoo
GNU/Linux.

Here are the highlights from a sysadmin point of view:

* FreeBSD = Kernel + Userland. All built from source
/usr/src.
  You update the base system by synchronizing that source
tree
  (with csup(1)), compiling it into /usr/obj and installing
that
  with a couple of make(1) commands. See /usr/src/UPDATING.

* Third party apps (including Xorg etc...) are easiest
  compiled and installed via /usr/ports into /usr/local.
  There's a clear separation between FreeBSD's own Userland
  and those third party apps: that's why you have e.g.
  /usr/local/bin/bash (a port app) vs. /bin/sh (a FreeBSD
  userland app). You update your ports by synchronizing
  /usr/ports (with csup(1) or portsnap(1)) and recursively
  rebuilding out-of-date or depending ports with tools like
  portupgrade, portmaster etc... See /usr/ports/UPDATING.

* You configure FreeBSD and third party apps' daemons
(which
  have startup scripts in /etc/rc.d and /usr/local/etc/rc.d
  respectively) by setting configuration variables in
/etc/rc.conf.
  Default settings for FreeBSD's confvariables can be found
in
  /etc/defaults/rc.conf; you just override them in
/etc/rc.conf.
  The variables you need to add to /etc/rc.conf for ports
are
  displayed when installing a port, but can also be found at
the
  beginning of the /usr/local/etc/rc.d/* startup scripts.

* FreeBSD's compiler is currently gcc + binutils, so you'll
  immediately feel at home.

Gentoo has been largely inspired by FreeBSD and uses a
similar
compile-everything-from-source approach; though gentoo is
IMHO
less comfortable installing the first time and maintaining.

Just remember that FreeBSD doesn't run the Linux kernel,
doesn't
use glibc etc...: it's a completely different code base. But
for
95% of all third-party software, its APIs are POSIX-ish
enough.

Last but not least: don't forget to ask on
freebsd-questions
and other mailing lists. Community support is excellent:
that
alone would be worth switching. ;)

I switched after using linux for several years because
things are more
consistent in FreeBSD. These days, I still use linux for
some things,
but it often feels like things are slightly weird and
kludgy. 

Which, in all honesty, they are. Linux is one of the
greatest projects
ever, creating different bits and pieces and putting them
together. But
sometimes, I just want things to work simply.

More sincerely, welcome to FreeBSD!  Set your mail
filters, subscribe to the lists, grab your handbook,
phasers on stun... Happy computing!

In my experience, it's both more stable and more up to date
than Debian.
Before FreeBSD, my primary OS choice was Debian, but
ultimately
everything I liked about Debian was even better with
FreeBSD.

The difficulty for my moving the last of my Linux boxes,
is...iscsi support.

God how I wish I could map luns, boot from luns, and share
lun love with my
other freebsd boxes.


Im starting on another venture, that I -want- on FreeBSD,
but likely will
not be able to, because I cant use iscsi on it.  (And wont
on Fbsd until its
been out for a while and proven stable).

But other than that, my move was painless, I -hate-
installing RH.

Read the FreeBSD handbook.

I found out that FreeBSD was much easier to follow (Files
and Such ) 
than Linux  about 9 years ago and have rarely looked back.
Unless of 
course when a client has Linux on a server or whatever.  If
you have run 
Linux than you can easily note the file names that are
different in 
FreeBSD.  You'll see that many  are the same.

Enjoy!

What about going to single user mode and editing /etc/passwd
so the 
"root" line has the username "uname"? Or
add user "uname" with UID 0?

The chown command would have looked up "uname" via
libnss and used the
numeric UID to alter the filesystem entries. The most you
could do here
is change the symbolic name for the "uname" user
and make the ls -l
output look different. Either way, you're stuck with the
files on the
filesystem not being owned by UID 0. I would highly
recommend not
mucking with /etc/passwd and letting rebuild world fix
things.
