The best way to upgrade my FreeBSD and its jails

[Redd Vinylene]

Thanks a lot guys for your great design insight!

I hope others will find this thread interesting as well. Here's the
final upgrade script I decided to use (my shell is zsh):

-

# FreeBSD/i386 mother.naoshige.net

csup /etc/cvsupfile

cd /usr/src

make buildworld buildkernel && \

mergemaster -p && \

make installworld installkernel delete-old delete-old-libs && \

mergemaster -i -U && \

JAILS=/usr/local/jails

cd /usr/src

for jail in $JAILS/*; do

  mergemaster -p -D $JAILS/$jail && \

  make installworld delete-old delete-old-libs DESTDIR=$JAILS/$jail && \

  mergemaster -i -U -D $JAILS/$jail && \

done

chflags -R noschg /usr/obj/*

rm -rf /usr/obj/*

-

Much obliged!
