yes, i do this:
1) make neccessary partitions and fs and mount them -- man parted,
man mkfs, may be man pvcreate, man vgcreate, man lvcreate, man mount)
2) copy files with xattrs, selabels, capabilities to new place (/boot
to new boot partition, / to new root partition, etc) -- man cp or man
rsync
3) change fstab on new system -- man vi or man nano
4) mount / and after that /boot (if exists) into /mnt and /mnt/boot respectively
5) mount --bind /dev /mnt/dev; mount --bind /sys /mnt/sys; mount
--bind /proc /mnt/proc
6) grub-install /dev/disk # /dev/disk is a device with new /boot part
7) umount all from /mnt
About 15 years ago similar process was used to deploy several hundreds
of new workstations from prepared tar of master image - simply boot
from livecd and unpack system to prepared mountpoint.
If you ask such questions - get some practice on virtual machine
before install on real computer.
