Hi list, I really need some help mounting an install.fs disk image, and hope someone can help :) I have been trying and failing to create an auto-installing USB flash drive for OpenBSD.
All of the below steps are being performed using an existing OpenBSD VM 1) Create /auto_install.conf file https://man.openbsd.org/autoinstall http://eradman.com/posts/autoinstall-openbsd.html - Done 2) Install 'upobsd' package pkg_add -i upobsd - Done 3) Inject newly created 'auto_install.conf' into a local 'bsd.rd' RAM disk upobsd -u /auto_install.conf -o /tmp/bsd.rd - Done 4) Add updated 'bsd.rd' file into 'install.fs' 4a) Associate image with a vnd device so disk image can be mounted as a filesystem image vnconfig vnd1 /home/sysadmin/install64.fs - Done 4b) Mount new vnd1c device (this is where I'm stuck) ****** Here is where I get lost. All the guides refer only to using install.iso (whos 'a:' and 'c:' partitions are ISO9660 filetypes - for CD based installs), but I need to use the install.fs (for USB based installs) ****** fw1# mount /dev/vnd1c /mnt mount_ffs: /dev/vnd1c on /mnt: Invalid argument fw1# mount -t cd9660 /dev/vnd1c /mnt mount_cd9660: /dev/vnd1c on /mnt: Invalid argument fw1# mount -t msdos /dev/vnd1c /mnt mount_msdos: /dev/vnd1c on /mnt: not an MSDOS filesystem fw1# mount -t ext2fs /dev/vnd1c /mnt mount_ext2fs: /dev/vnd1c on /mnt: Input/output error As you can see, none of the the types I know about are working? bsd1# disklabel vnd1 # /dev/rvnd1c: type: vnd disk: vnd device label: fictitious duid: e5445c1e269855f0 flags: bytes/sector: 512 sectors/track: 100 tracks/cylinder: 1 sectors/cylinder: 100 cylinders: 7382 total sectors: 738240 boundstart: 1024 boundend: 737280 drivedata: 0 16 partitions: # size offset fstype [fsize bsize cpg] a: 736256 1024 4.2BSD 2048 16384 16142 c: 738240 0 unused i: 960 64 MSDOS I cannot work out what the filesystem should be? It shows as 'unused' here. NB; If I try with the 'install.iso' disk image the vnd mount works fine (with '-t cd9660'). But I need this to work for a flash drive? Assuming I could get past this, I think I would then need to do the following; 4c) Copy in bsd.rd cp /tmp/bsd.rd /mnt/ 4d) Unmount /mnt umount /mnt 4e) Disassociate vnd1 vnconfig -u /dev/vnd1 6) copy modified install.fs image to USB flash.. dd if=install*.fs of=/dev/rsd6c bs=1m Thanks in advance for your time and help. Andy.
