Creating freeBSD vds or vps with zfs developed by Sun™

Recommend to make with 2nd disk
it is a example just we can create...
if you create zfs in main host disk, i am sure u cant boot next reboot :P

Note: putting " & " for backgroud process. even we got disconnect from interenet, the process remain in remote server as background. helpful for Myanmar users who are using internet from stupid no stable internet connection provider. like ME. lmao rofl

FreeBSD boot error howto rescue

Yesterday i got some freeezzz my box fvkBSD while changing in loader.conf
If something wrong loader.conf, we can rescue setting from boot loader.
To fix variable setting:

1. reboot fvkBSD box
2. FreeBSD boot menu -> Press 6 to select "Escape to loader prompt"
3. In loader prompt, type: "show" there u can see loader setting. press page down and search wrong setting that you set before.
4. fix correct type: "set (variable)=(correct value)"
5 after set value, type: boot

Good Luck...

http:// mirror instead of ftp:// for pkg manage

all you know our myanmar users restrict ftp ports, i got problem too.. when i use pkg_add package in freebsd... so i would like to advice to replace http mirror instead of ftp..

if you are using bash shell..
# export PACKAGEROOT='http://ftp.FreeBSD.org'

if you are using csh default shell...
# setenv PACKAGEROOT='http://ftp.FreeBSD.org'

i hope that will help you more... :P
