Dale Scheetz said: If you use loop devices at all you will certainly want more than one. My system has loop0 thru loop7. As does mine. 'MAKEDEV loop' creates them all (at least, it did on my Debian 1.1 system). This would allow your mount to look like: mount -o loop=/dev/loop2 -t ext2 /path/to/file /mount/point That works too. My way (mount -o loop -t ext2 ...) make mount choose the first available loop device.

Mounting a file as a filesystem
Hi all, I have two disks on my PC, hda=127 MB and hdb=1.6 GB. I am using hda for Debian, hdb is Win95. I installed Debian on hda as a test and promptly fell in love with it. Unfortunately I earn my living developing for Win 3.x/Win 95 and so cannot easily repartition my main disk. I heard some noise on this list about setting being able to mount a file as a filesystem. I would like to know how I can create say a 200MB file on hdb (Win 95) and mount it as a filesystem on say /usr. Is this possible?

I would like to know how I can create say a 200MB file on hdb (Win 95) and mount it as a filesystem on say /usr. Doesn't sound like a good idea to use a mounted file as a Linux file system. Nothing compares to a real ext2 file system. ;-) If i were you i'd rather repartition by using FIPS-1.5 which does no harm to your existing data. You can get the most recent information and version at it's homepage at http://www.student.informatik.th-darmstadt.de/~schaefer/fips.html;. I think Debian distributions normally provide FIPS but not the most recent version with all (minor) bugfixes included. I regularily use FIPS for splitting harddisk partitions (20 times so far) and never managed to get data destroyed on any up to now. FIPS is a very secure tool and makes it possible to undo a partiton splitting without doing harm to the data on it. Works well with Win95 vfat file systems.

Partition Magic will repartition a DOS or win95 volume without destroying data. It is also very easy to use.

As far as i have understood it from reading it's documentation it can only split DOS/VFAT and nothing more. I remember that it stated something about OS/2 but don't know.

Re: Mounting a file as a filesystem
The loop device is pretty nifty. I use it to maintain a root-disk image used on a special-purpose diskless machine. To make changes to the root disk, i mount the image, update the FS, unmount it, compress it, and copy the compressed file to a floppy. Then i can bootstrap the system from that new and improved compressed root disk. This works great, except for one annoying detail. After some amount of editing the root fs in the file, the mount count exceeds the routine fsck threshold, and the next time i commit the image to my root floppy and boot off it, the system complains when mounting the file system: maximum mount count exceeded or something like that. So my question is this: how do i fsck the filesystem in a file? TIA Sebastian Kuzminsky [EMAIL PROTECTED] -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] .
