[gentoo-user] Moving the system from one disk to another

[meino.cramer@gmx.de]

Hi,

I have to move my whole system from one disk to another
bigger one.

I think of doing as follows:
Boot a system via CD/DVD (knoppix for example).
Mount small disk read-only 
Mount bigger disk read-write

cd into mountpoint of the first one
cp -a . ../<mountpoint_of_bigger_disk>

Seems to me slow but correct? Or?

(I have to set the bootable flag of the correct partion
additionally...)

I dont want to have a booting system afterwards, which "runs" for --
say -- three month and suddenly hit a obscure bug due to my
copy-commands, which only did it to 99.87% correct... ;)

I would like to preserve as much as possible of the file/directoy
times ,,,

Or does a mystical command with s-tar a better job faster? 

Thank you very much in adance for any help!

Best regards,
mcc
