Hello,
After 3 hours, i made my bootable FreeBSD CD/Floppies. Actually, i
finished my install.cfg but i have a problem because i don't
understand the final step :
I'm not sure I do either, but I'm willing to attempt to help. Bearing
in mind IANAE, I *think* this is what you're seeing:
# mkdir /img
# cd $CHROOTDIR/R/cdrom/disk1/floppies
Should be self-explanatory; $CHROOTDIR should be set in the
environment if you are doing "make release"....
/* Get mfsroot.gz from mfsroot.flp */
# vnconfig /dev/vn0c mfsroot.flp
# mount /dev/vn0c /img
# cp /img/mfsroot.gz .
# umount /img
# vnconfig -u /dev/vn0c
Create a "memory disk" from the floppy image "mfsroot.flp",
mount it, copy the "mfsroot.gz" to the current working dir,
unmount it and destroy the "memory disk".
/* Unzip mfsroot.gz to get mfsroot */
# gunzip mfsroot.gz
Obvious, I hope.
/* Put your config file in mfsroot */
# vnconfig /dev/vn0c mfsroot
# mount /dev/vn0c /img
# cp install.cfg /img/.
# umount /img
# vnconfig -u /dev/vn0c
/* (If you 'gzip mfsroot' here, you can use that for bootable
mfsroot.flp for floppies) */
Mount the unzipped "mfsroot" file in a memory disk,
cp your install.cfg to this memory disk, unmount it
and destroy the memory disk.
(Note of concern ... I don't see this getting moved
back to anywhere were it will do some good before moving
to the next step. Where did you get these instructions?)
/* Put mfsroot in kernel so that it will read it when boot time */
# vnconfig /dev/vn0c boot.flp
# mount /dev/vn0c /img
# cp /img/kernel.gz .
# gunzip kernel.gz
# write_mfs_in_kernel -f kernel mfsroot
/* write_mfs_in_kernel can be found at /usr/src/release. Compile it
if you haven't. */
# gzip kernel
# cp kernel.gz /img/.
# umount /img
# vnconfig -u /dev/vn0c
Mount the "boot.flp" image in a memory disk, grab the kernel,
unzip it, add the altered "mfsroot" to the kernel using the
write_mfs_in_kernel program/script, zip up the new kernel, copy it to
the image and unmount said image.
I'm concerned though about this documentation; for one thing
vnconfig is deprecated (except for 4.X releases, which are, uh,
deprecated<?>), and "write_mfs_in_kernel" was "nuked" from CVS **8
years ago** by the venerable jkh himself, so I have to wonder, "Where
did this 'how-to' come from?"
You may need someone more familiar with the modern RELENG
system to help with this....

Thank you for your answer. I found these instructions at
