formating a filesystem with python

Ricardo Tiago

Hi all,

is there a package in python that allows to mount/umount and format
(to ext3) a filesystem? I know that this is possible by just calling
the os commands 'mount/umount and mkfs' but this would imply to have
to change sudoers to run the script as non-root.

Thanks
Ric

well, that's a very sensible unix-restriction. and you can't overcome that.

IOW: no, there is no such thing.

You can use pexpect to become root without changing sudoers. Assuming
you know the root password...

I understand that this is a very sensible unix question but i think
fuse does this at least it mounts. I was wondering if there were other
packages with similar functionality.

I don't know what fuse is.

And *mounting* can be allowed to be made by users. and possibly there is
a mount-daemon that can mount e.g. usb-devices. but that wouldn't be a
pure python-module-solution either.

On Linux (I guess that"s the target OS as you mentioned ext3) mounting
could be done as non-root using FUSE or HAL (maybe using a frontend
like gio or kio) if the system supports that, or with an appropriate
fstab entry.

Maybe HAL can configured to do mkfs but that has to be done very
carefully to avoid security problems.

Maybe you could use something like AppArmor, too.

Most likely you get better answers by first asking in a Linux group
how to do this things without root privileges and then come back to
ask how to do it with Python.

Has anyone released a Python "mock filesystem" for automated testing?

by: Peter Hansen | last post by:

The term "mock filesystem" refers to code allowing unit or acceptance tests to create, read and write, and manipulate in other ways "virtual" files, without any actual disk access. Everything is held in memory and therefore fast, without risk of damaging real files, and with none of the messiness of leftover files after testing. Googling the archives and the web suggests that only I and Remy Blank have done much along these lines. I...

running postgresql database from loopback filesystem?

I have virtual hosted users on a server and some of them have a postgresql database. I'm concerned about the outside possibility that a user could create an infinite loop and fill up the partition on which everyone's database resides. Anyway, it occured to me that I could create a special file for each database user of limited size, and make a filesystem on top of that file. The file could be owned by the user. Then, each user could have...

In need of a virtual filesystem / archive

by: Enigma Curry | last post by:

I need to store a large number of files in an archive. From Python, I need to be able to create an archive, put files into it, modify files that are already in it, and delete files already in it. The easy solution would be to use a zip file or a tar file. Python has good standard modules for accessing those types. However, I would tend to think that modifying or deleting files in the archive would require rewriting the entire archive. ...
