However I did come across a weird problem. I’d installed Debian linux and the console keyboard layout wasn’t correct for my Apple USB keyboard.
The solution was to use this command
dpkg-reconfigure console-data

Boot from any emergency boot/root disk set. (SystemCD, rescue cd). If /dev/hda3 is the original root partition, the following will let one edit the password file juist as:
#mkdir fixit
# lvm vgchange -a y
# lvdisplay
#mount /dev/debain/root fixit
#cd fixit/etc
#vi passwd

show all dev

To activate the LVMs in FC4 Rescue Mode, run this from the command line:
lvm vgchange -a y
For a list of LVM commands, run:
lvm help

It is designed to upload files to, and run shell commands on, a number of servers in parallel or serially. These commands are grouped in tasks (regular python functions) and specified in a ‘fabfile.’
This is called remote automation, and the primary use case is deploying applications to multiple similar hosts.
Although it is easier to automate […]

If you need more information about LVM, you might be […]

Internal and external NTFS partitions are different: NTFS partitions don’t mount read-write by default. You can arrange for an internal drive to mount read-write permanently by making a permanent entry in the file system table (fstab). You can’t do that for an external NTFS partition because if it’s switched off when the system boots, the […]
