I've created a partition with GNU Parted, how do I mount the partition?
The manual information at http://www.gnu.org/software/parted/manual/parted.html is good, but I am sure about how I mount the partition afterwards.
Thanks,

Dear Brothers
First i installed suse linux with the following partition. my hd0 size is 75gb
hdc1 swap 1 gb
hdc2 native linux 39gb
For the rest of the 35 gb i did not create any partition. so i planned to install solaris 10x86 on that free space.
When i installed the solaris i... (1 Reply)
I dualboot Ubuntu and Fedora in one hard drive. Below are the scenario.
First, installed Ubuntu 10.4 on the entire disk (40GiB of size).
Then, shrink the Ubuntu installation to equal size to free up space for fedora.
Second, installed Fedora 13 using the option "Use free space on selected... (2 Replies)

I want to gain read/write access to a Windows 8 partition from a linux live cd. Prior to Windows 8, I used ntfs-3g to mount the partition from the command line.
The "Fdisk -l" command does not seem to be able to read efi partitions. There must be some new strategy for linux users. This is... (6 Replies)
Hi,
In Linux, I had modified fstab file which used to mount ~/Music, ~/Pictures, etc with disk partitions containing corresponding content or binding directory located at other partition. But I am wondering can I do same in El-Capitan as well? No linking!

bup-margin
bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
