so if i install from binaries i should do:
newfs -U -O 2 /dev/da1s1a
mount /dev/da1s1a /mnt
dump 0buf 126 - / | restore xbf 126 -
can someone please explain what these commands are doing? will i lose data that is on the device? if i go through the make buildworld/make installworld process then do i still need to do this to update to UFS2??
what significance does this:
1.18. My /boot/loader reports "Invalid format"?
from the above article hold for me. is it likely to happen? i read through the /usr/src/UPDATING document for 5.x when i tried to install on my laptop, but still couldn't manage to upgrade from 4.10 to 5.3 without errors. i can't afford to do that on my current system because i need it for work and uni.
do i have to just back up all my data, install 5.3, format the hard drive and then reinstall all my applications? it'll take ages...
