<
< cd /tmp/b/

< cpio -oc > /tmp/a/x86.miniroot-modified
Shouldn't need this cpio. Just unmount /tmp/b and gzip again.
what I've usually done is copy the x86.miniroot to x86.miniroot.to.change
do the ungzip/lofiadm/mount on the x86.miniroot.to.change
unmount this lofi mount
and then just gzip the x86.miniroot.change
Here I change the etc/motd in the miniroot:
(I'm using the safe miniroot, but its the same with the install miniroot,
btw, don't replace the original safe miniroot !)
#
# gzip -dc /boot/x86.miniroot-safe > x86.miniroot.to.change
# mkdir mnt
# lofiadm -a `pwd`/x86.miniroot.to.change
/dev/lofi/1
# mount /dev/lofi/1 `pwd`/mnt
# cd `pwd`/mnt/etc
# ls -l motd
-rw-r--r-- 1 root sys 53 Dec 20 18:07 motd
# echo "Hi Ya" >> motd
# ls -l motd
-rw-r--r-- 1 root sys 59 Jan 12 20:29 motd
# cd ../..
# umount `pwd`/mnt
# lofiadm -d /dev/lofi/1
# gzip x86.miniroot.to.change
#
# # and just to be sure mount it again..
#
# gzip -d x86.miniroot.to.change.gz
# lofiadm -a `pwd`/x86.miniroot.to.change
/dev/lofi/1
# fstyp /dev/rlofi/1
ufs
# mount /dev/lofi/1 `pwd`/mnt
# cat `pwd`/mnt/etc/motd

Hi Ya
#
after all this, the gzip'd filesizes are:
# ls -l x86.miniroot.to.change /boot/x86.miniroot-safe
-rw-r--r-- 1 root root 59044958 Dec 23 17:19 /boot/x86.miniroot-safe
-rw-r--r-- 1 root root 59040281 Jan 12 20:33 x86.miniroot.to.change
bash-3.00#
Regards,
<
< but the file sizes are different:
<
< 154050560 bytes for x86.miniroot (original)
< 132227072 bytes for x86.miniroot-modified
<
< and
<
< lofiadm -a /tmp/a/x86.miniroot-modified
< mount /dev/lofi/2 /tmp/c/
<
< gives the
<
< mount: /dev/lofi/2 is not this fstype
<
< which tells me my cpio flag's not set right, etc.
<
< Any quick clues on what's the best way to zip the miniroot back up into
usable form?

< Thanks alot,
