Actually the live-image didn't resize the CF card either, the missing piece in my case was the resize_disklabel script (https://github.com/NetBSD/src/blob/trunk/distrib/utils/embedded/files/resize_disklabel), which wasn't there by default (in rc.d). Once there, the following in rc.conf is doing the job: resize_disklabel=YES resize_root=YES resize_root_flags="-p" resize_root_postcmd="/sbin/reboot -n" br0nko

I confirm that the image is bootable with your patch, thank you !!! As you said
already, it lack the resize capability, which make the image somehow useless
since it run out of space at first boot. I did try "resize_root=YES" in rc.conf
without any luck.
I did end-up by using the live-image. The only missing piece for me was the
"fstab_minwrites" (which is still relevant in 2022 seeing the price of CF card).

i386/amd64 image generated trough mkimage stuck on primary bootsrap at boot
Hi,
I wanted to resurrect an old i386 alix box, and I did follow the guide to
create a custom image trough mkimage
(https://www.netbsd.org/docs/guide/en/chap-inst-media.html#chap-inst-media-creating-live-images).
I did first try on amd64 so that I can first test on my laptop. Build was
successful but when I boot the USB key, I'm stuck on primary bootstrap
("NetBSD/x86 ffsv1 Primary Bootstrap"), no error. However I can boot it from
grub (installed on the laptop hard-drive) , image is fully functional that way.
Here's what fdisk show:
=
bash-5.1# vndconfig vnd0 /home/phil/alix-netbsd.9.2.img
bash-5.1# fdisk -vv /dev/rvnd0
Disk: /dev/rvnd0
NetBSD disklabel disk geometry:
cylinders: 765, heads: 64, sectors/track: 32 (2048 sectors/cylinder)
total sectors: 1568447, bytes/sector: 512
BIOS disk geometry:
cylinders: 98, heads: 255, sectors/track: 63 (16065 sectors/cylinder)
total sectors: 1568447
Partitions aligned to 16065 sector boundaries, offset 63
Partition table:
0: NetBSD (sysid 169)
start 63, size 1568384 (766 MB, Cyls 0/1/1-97/160/62), Active
beg: cylinder0, head 1, sector 1
end: cylinder 97, head 160, sector 62
Information from PBR:
Not bootable: All bytes are identical (0x00)
Not bootable: Bad magic number (0x)
1: (sysid 0)
start 0, size 0
beg: cylinder0, head 0, sector 0
end: cylinder0, head 0, sector 0
2: (sysid 0)
start 0, size 0
beg: cylinder0, head 0, sector 0
end: cylinder0, head 0, sector 0
3: (sysid 0)
start 0, size 0
beg: cylinder0, head 0, sector 0
end: cylinder0, head 0, sector 0
First active partition: 0
Drive serial number: 0 (0x)
=
I did try to reinstall the primary bootstrap:
installboot -v -o timeout=5 /dev/rsd0a /usr/mdec/bootxx_ffsv1
But it didn't fix the problem either.
I'm running out of ideas, I don't really see what I'm missing. Any help would
be highly appreciated.
