-Install grml to harddisk:
-
-# grml2hd
-
-Notice: You can pre-select the partition for the partition selector
-and mbr dialogs inside grml2hd using:
-# grml2hd /dev/hda1 -mbr /dev/hda
-
-See: man grml2hd + http://grml.org/grml2hd/
-
-Tags: grml2hd, installation
---
-Install grml on software RAID level 1:
-
-Create /dev/md0 (and some more /dev/md* devices) first of all:
-# cd /dev && MAKEDEV dev
-
-Create RAID:
-# mdadm --create --verbose /dev/md0 --level=raid1 \
- --raid-devices=2 /dev/hda1 /dev/hdc1
-
-Finally install grml on it:
-# SWRAID='mbr-only' grml2hd /dev/md0 -mbr /dev/md0
-
-See: man grml2hd + http://grml.org/grml2hd/
-
-Tags: grml2hd, installation, mdadm, raid
---
-Install grml in non interactive mode with grml2hd:
-
-Adjust configuration as needed:
-# vim /etc/grml2hd/config
-
-Then execute:
-
-# GRML2HD_NONINTERACTIVE=yes grml2hd
-
-or run:
-
-# grml2hd -i
-
-Use with care and only if you really know what you are doing!

-Install (plain) Debian (sarge release) via grml:

-Assuming you want to install Debian to sda1:
-
-mkfs.ext3 /dev/sda1 # make an ext3 filesystem on /dev/sda1
-mount -o rw,suid,dev /dev/sda1 /mnt/test # now mount the new partition
-debootstrap sarge /mnt/test ftp://ftp.tugraz.at/mirror/debian # get main packages from a debian-mirror
-chroot /mnt/test /bin/bash # let's chroot into the new system
-mount -t devpts none /dev/pts # ...otherwise running base-config might fail ("Terminated" or "openpty failed")
-mount -t proc none /proc # make sure we also have a mounted /proc
-base-config # now configure some main settings
-vi /etc/mkinitrd/mkinitrd.conf # adjust $ROOT (to /dev/sda1) for your new partition, autodetection will fail in chroot
-cd /dev ; ./MAKEDEV generic # make sure we have all necessary devices for lilo
-apt-get install lilo linux-image-2.6.12-1-386 # install lilo and a kernel which fits your needs
-cp /usr/share/doc/lilo/examples/conf.sample /etc/lilo.conf # let's use a template
-vi /etc/lilo.conf && lilo # adjust the file for your needs and run lilo afterwards
-umount /proc ; umount /dev/pts # we do not need them any more
-exit # now leave chroot
-cp /etc/hosts /etc/fstab /mnt/test/etc/ # you might want to take the existing files...
-cp /etc/network/interfaces /mnt/test/etc/network/ # ...from the running grml system for your new system
-umount /mnt/test && reboot # unmount partition and reboot...

Convert files from Unicode / UTF-8 to ISO:

cfdisk /dev/hda # create a partition with type 8e (lvm)
pvcreate /dev/hda2 # create a physical volume
-vgcreate resize_me /dev/hda2 # create volume group
-lvcreate -n resize_me -L100 resize_me # create a logical volume
-mkfs.ext3 /dev/resize_me/resize_me # now create a new filesystem
-mount /dev/resize_me/resize_me /mnt/test # mount the new fs for demonstrating online resizing
+vgcreate vg0 /dev/hda2 # create volume group
+lvcreate -n resize_me -L1G vg0 # create a logical volume
+mkfs.ext3 /dev/mapper/vg0-resize_me # now create a new filesystem
+mount /dev/mapper/vg0-resize_me /mnt/test # mount the new fs for demonstrating online resizing
df -h # check the size of the partition
-lvextend -L+100M /dev/resize_me/resize_me # let's extend the logical volume
-resize2fs /dev/resize_me/resize_me # and finally resize the filesystem
