2.4. Mounting the New Partition

Now that a file system has been created, the partition needs to be made accessible. In order to do this, the partition needs to be mounted at a chosen mount point. For the purposes of this book, it is assumed that the file system is mounted under /mnt/hlfs, but the directory choice is up to you.

Choose a mount point and assign it to the HLFS environment variable by running:

export HLFS=/mnt/hlfs

Next, create the mount point and mount the HLFS file system by running:

mkdir -pv $HLFS
mount -v -t ext3 /dev/<xxx> $HLFS

Replace <xxx> with the designation of the HLFS partition.

If using multiple partitions for HLFS (e.g., one for / and another for /usr), mount them using:

mkdir -pv $HLFS
mount -v -t ext3 -o acl,user_xattr /dev/<xxx> $HLFS
mkdir -v $HLFS/usr
mount -v -t ext3 -o acl,user_xattr /dev/<yyy> $HLFS/usr

Note that the -o acl,user_xattr options are required in order to use POSIX file capabilities to drop root priviledges for SUID-root programs.

Replace <xxx> and <yyy> with the appropriate partition names.

Ensure that this new partition is not mounted with permissions that are too restrictive (such as the nosuid, nodev, or noatime options). Run the mount command without any parameters to see what options are set for the mounted HLFS partition. If nosuid, nodev, and/or noatime are set, the partition will need to be remounted.

If you are using a swap partition, ensure that it is enabled using the swapon command:

/sbin/swapon -v /dev/<zzz>

Replace <zzz> with the name of the swap partition.

Now that there is an established place to work, it is time to download the packages.
