You could try using a "dump -f - ufsfs.img | restore -if -" pipeline; dump to read the filesystem and restore -i to give you a simple navigation interface.

Mount an iso image?
Is it possible to mount an iso image? I'm not referring to a cd, but a single file that has been created using mkisofs. If so, what command would you use? mount_cd9660 wants a block device.

This works for me on 5.4... mount_cd9660 -o ro /dev/`mdconfig -a -t vnode -f /path/to/file.iso` /mount-point and hopefully won't have dramatic consequences if the mdconfig fails! I don't have any 4.x systems so you'd have to compare the options for vnconfig(?) if that's what you have. I don't have the script-fu to suggest how you might set about undoing it all in one line, since you'd have to do an unmount before you could perform the required mdconfig -d, and hence lose the chance to do something like: mdconfig -d -u`mount | grep "/mount-point" | cut ... ` so you'd probably have to script it. Although ... set mdvar=`mount | grep "/mount-point" | cut -c 8-8` && umount /mount-point && mdconfig -d -u $mdvar && unset mdvar seems to work (but comes with a multitude of disclaimers about fitness for purpose and possible health risks!). Hopefully you're not looking for command-line shortcuts.

Re: Can I mount an ISO image directly with mount?
OK, here's how you do it on Linux: # mount -o loop -t iso9660 eg.: # mount -o loop -t iso9660 /home/steven/5.4-RELEASE-i386-disc1.iso /var/ftp/pub/freebsd-5.4/ Apparently, however this doesn't work on FreeBSD. AFAIK, this should work: # mdconfig -a -t vnode -f -u 0 # mount -t cd9660 /dev/md0 eg.: # mdconfig -a -t vnode -f /home/steven/5.4-RELEASE-i386-disc1.iso -u 0 # mount -t cd9660 /dev/md0 /var/ftp/pub/freebsd-5.4/ Regards, -- Can Berk Guder Sabanci University Istanbul, Turkey Quoting Steven Friedrich <[EMAIL PROTECTED]>: > I believe I read a posting over a year ago, that stated that you could mount > > an ISO file directly with mount. > > I searched the archives but couldn't find it. > I searched the FAQ and handbook as well. > > I do see a section in the handbook about doing it with vn, but I want to know > > if it's possible with mount alone. > > -- > i386 FreeBSD 4.11-STABLE > There are 10 types of people in this world.

Can I mount an ISO image directly with mount?
I believe I read a posting over a year ago, that stated that you could mount an ISO file directly with mount. I searched the archives but couldn't find it. I searched the FAQ and handbook as well. I do see a section in the handbook about doing it with vn, but I want to know if it's possible with mount alone. -- i386 FreeBSD 4.11-STABLE There are 10 types of people in this world.

I had once heard a friend tell me that he used to create ISO images in this very way in Linux by mounting an ISO image on a (Linux) loop device and then copy files to the image. It seems like it could be a flexible and convenient way to quickly create an ISO image at random, but I've never been able to get FreeBSD to mount and ISO image rw using either vnconfig or mdconfig.

Normally one would use /usr/ports/sysutils/mkisofs to create a new ISO image containing the modified files and burn that ISO image on CD. However, the man page for mount_cd9660 (in FreeBSD release 4.9) gives this example usage of the command: The following command can be used to mount a Kodak Photo-CD: mount_cd9660 -o rw -v -s 0 /dev/cd0c /cdrom This might be a bad example. Neither the man page for mount_cd9660 nor the man page for mount lists "rw" as option specifiable with the "-o" flag. The "-w" flag (which is not an "option") is listed on the mount man page but not on mount_cd9660 man page. I was under the impression that the mount_cd9660 command only mounted file systems read-only.

mount an ISO image on rw mode
Hello users, Perhaps I am just being stupid, doing a lot of things at the same time, thus losing it. Am I just dreaming by imagining that I can mount an ISO image with write access? I have done [EMAIL PROTECTED] /dev/vn0c /wananchi/FreeSBIE-1.0-i386.iso [EMAIL PROTECTED] /dev/vn0c /freesbie This mounts the image in read-only mode. However, I would like to modify a few files on the image before writing it to a CD. The man page for mount says that I could use -o -w to achieve a write mode. Does this also apply to ISO iamages? I was thinking that once mounted, they should behave like regular files, no? -Wash http://www.netmeister.org/news/learn2quote.html -- +==+ |\ _,,,---,,_ | Odhiambo Washington<[EMAIL PROTECTED]> Zzz /,`.-'`'-. ;-;;,_ | Wananchi Online Ltd. www.wananchi.com |,4- ) )-,_. ,\ ( `'-'| Tel: +254 20 313985-9 +254 20 313922 '---''(_/--' `-'\_) | GSM: +254 722 743223 +254 733 744121 +==+ After an instrument has been assembled, extra components will be found on the bench. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
