doing 'make installworld / installkernel' a second time?

[Matthias Apitz]

Hello,

I've created a bootable USB key with -CURRENT like this:

# mkdir -p /usr/src/CURRENT/obj
# cd /usr/src/CURRENT
# setenv CVSROOT :pserver:anoncvs at anoncvs.fr.FreeBSD.org:/home/ncvs
# cvs login  
# cvs checkout src
# cd /usr/src/CURRENT/src
# setenv MAKEOBJDIRPREFIX /usr/src/CURRENT/obj
# make buildworld
# make buildkernel KERNCONF=GENERIC

(USB key inserted as /dev/da0)

# fdisk -I da0
# fdisk -B da0
# bsdlabel -w da0s1 auto
# bsdlabel -B da0s1
# newfs /dev/da0s1a
# mount /dev/da0s1a /mnt
# make installworld  DESTDIR=/mnt
# make installkernel DESTDIR=/mnt KERNCONF=GENERIC INSTALL_NODEBUG=t
# make distrib-dirs  DESTDIR=/mnt
# make distribution  DESTDIR=/mnt
# echo /dev/da0s1a / ufs rw 1 1 > /mnt/etc/fstab
# cat <<EOF-EOF-EOF > /mnt/etc/rc.conf
wlans_ath0="wlan0"
ifconfig_wlan0="WPA DHCP"
hostname=tinyCurrent
sshd_enable="YES"
EOF-EOF-EOF
# cp /etc/wpa_supplicant.conf /mnt/etc
# umount /mnt

the resulting USB key boots fine;

what I'm unsure about is: can I copy /usr/src/CURRENT onto the key with

# cp -rp /usr/src/CURRENT /mnt

and when it is booted (in my EeePC) can I do there the installation to the
SSD again with

# newfs -m 0 -o space /dev/ad2s1a
# mount /dev/ad2s1a /mnt
# setenv MAKEOBJDIRPREFIX /CURRENT/obj
# cd /CURRENT/src
# make installworld  DESTDIR=/mnt
# make installkernel DESTDIR=/mnt KERNCONF=GENERIC INSTALL_NODEBUG=t
# make distrib-dirs  DESTDIR=/mnt
# make distribution  DESTDIR=/mnt

or is /CURRENT/src and /CURRENT/obj not enough for the 2nd installation,
for example because the 1st 'make installworld' has removed stuff below
/usr/src/CURRENT/obj?

Thx
