I have had a reason to run Linux, and have been running
FreeBSD for
nearly 10 years, so I'm backwards to your situation.

Personally, I find it difficult to operate under a Linux
platform, and
I'll explain why without trying to start a flame war.

My boxes that run FreeBSD do not have a GUI. I found that
many of the
Linux commands, start up scripts, configuration files et-al
were in
the Wrong Place (relative).

Essentially, it's as simple as that. If you want to cross
platforms
like I've had to do from time to time, the majority of stuff
comes
near-naturally, and what doesn't, Google will take up the
slack.

You have come to a good place if you need to move forward
with FBSD,
and especially with a 10 yr background in *nix to begin
with, a little
time in frustration of learning the new locations of files
it should
be a cakewalk.

What to read? Start with the FreeBSD handbook. One could say
that it's
TFM to begin with ;)

I have very little experience of Linux; I 'found' FreeBSD
long before
I had even heard of it! I read an article recently which
expresses
what it was like for someone who recently converted:

http://penguinpetes.com/b2evo/index.php?title=the
_bsd_community_compared_to_the_linux_&more=1&c=1&
;tb=1&pb=1

I've heard some Linux users complain about the installer.
Words like
"arcane" were used. If you think you may struggle
with that, then may
I reccommend PC-BSD. I've been using it on a spare PC for a
while now
and really like it. It's installer is better than any of the
few Linux
distros I've tried. It's based on FreeBSD of course (Stable
I believe).

As for what to read; The Handbook is a must:

JUST MY STORY.. I MOVED TO FREEBSD FROM LINUX FIVE YEARS
AGO. SHELL IS
ONLY THING I FELT DIFFICULT. BUT NOW I AM USING TCSH INSTEAD
OF BASH.
ASIDE FROM THAT, EVERYTHING IS OK ;;

Hi,
No I am not able to login as root from other consoles also.

I am able to ssh on this machine from other machines and is
able to 
successfully login to this machine but from my console I am
now even not able 
to login to this machine. It is not accepting my uname and
passwd. Looks like 
I ma stuck at a big trouble.

Hi,

Thanks a lot!!!
The fix you provided worked for me, I am able to switch from
normal user to su 
but this I am able to do with the help of ssh login only. I
am not able to 
login from my console. When I am trying to login from my
console it is not 
accepting my username and password not even of root. Giving
an error message 
of Login Incorrect. Below are the log messages which I am
getting.

Friends... thank you for all of your responses. Last night I
read a big 
chunk of the handbook and read articles such as 
http://www.over-yonder.net/~fullermd/rants/bs
d4linux/bsd4linux1.php  Very 
helpful. I was impressed with the quality of the
documentation and I like 
the disciplined approach to FreeBSD.

The more I read, the more I was convinced that FreeBSD was
what I was 
looking for and would satisfy some of my
needs/disillusionment with Linux. 
I look forward to putting it on a box and starting the learn
the 
differences. Many thanks again!

I have used Linux for almost 10 years before switching to
FreeBSD. A lot
of the things that I leared while making the switch are
documented on my
FreeBSD webpage; http://www.xs4a
ll.nl/~rsmith/freebsd/

Some highlights;
- services must be enabled in /etc/rc.conf
(foo_enable="YES")
- devices permissions are set in /etc/devfs.conf and
/etc/devfs.rules
- build third party applications from ports, it'll save you
a lot of
  trouble
- mounting filesystems as a non-root user has certain
requirements;
  * the sysctl(8) vfs.usermount must be set to 1.
  * the user or a group that he belongs to must have
read/write
    permission on the device
  * the user must _own_ the mount point

HTH,
Roland

Hi
Using freeBSD is more fun. Installing packages and all that
is very easy. The 
things you can do in LINUX you can surely do with FreeBSD.
Collection of 
large number of ports and the flexibility to modify anything
the way you want 
make it cool. Really after installing FreeBSD I had never
swithched back to 
LINUX.
Hope you will also enjoy working on it.

I've been a Linux user for more than 6 years until 4-5
months ago when
I found some old 20GB HDD and decided to give FreeBSD a try.
 Believe
it or not after 1 month of playing with FreeBSD I removed my
Linux
installation from the main HDD and installed FreeBSD as the
main and
only OS on my machine!  So, as you can see it'll be an easy
shift for
an average Linux user -like me.

In fact many concepts are similar to those of Linux however
there are
differences.  What I did for learning FreeBSD was
1. Reading the documentation -when required- that is bundled
in FreeBSD
installation disks and also is available online on
www.freebsd.org.
2. Reading man pages.
3. Subscribing to Questions, Current and Stable mailing
lists
(www.freebsd.org).

You're not likely to become a FreeBSD expert in 1 month but
in my
experience I was feeling friendly and at home in FreeBSD
after about
1.5 months.
