Update Archlinux Hemat Bandwith dengan Deltup

Sebagai distro rolling release, Arch Linux memang menuntut untuk sering-sering update sistem. Bagi yang punya koneksi dewa tentu gak masalah. Tapi bagi yang koneksinya pas-pasan, apalagi terbatas quota, perlu cari cara untuk sedikit lebih ngirit bandwith.

Cara menyiasatinya bisa dengan deltup (delta update). Intinya, delta hanya akan mendowload perbedaan atau selisih antara versi paket yang telah terinstal dengan versi paket yang baru, kemudian menggabungkan ulang (rebuild). Berikut langkah instal dan setting deltup di Archlinux kita.

1. Instal paket xdelta3
# pacman -S xdelta3
2. Edit file /etc/pacman.d/mirrorlist, masukkan repo yang mendukung delta, salah satunya repo Delta Archlinux.fr

##
## Arch Linux repository mirrorlist
## Generated on 2011-03-24
##

## Delta Archlinux.fr
Server = http://delta.archlinux.fr/$repo/os/$arch
.....

3. Sebelum mengaktifkan repo delta, kita bisa cek dulu, gimana bedanya sebelum dan sesudah memakai deltup.

Proceed with installation? [Y/n]

Setelah menggunakan deltup, update menjadi 343,15 MB.
Itu tadi langkah-langkahnya. Perlu diperhatikan, terkadang (hanya beberapa kasus sih) delta gagal untuk rebuild paket, jadi terpaksa harus donlot dan instal manual.

Boot File ISO Langsung dari GRUB2

Tujuan: booting CD installer atau LIVE CD GNU/LINUX tanpa harus membakar ke CD atau flashdisk.

Bahan2 percobaan:
1. File ISO Puppy Linux,
2. GRUB2 yang sudah terinstal (Saya pake GRUB2 di Ubuntu Lucid).

Langkah-langkah:

1. buka /etc/grub.d/40_custom (sebagai root)
2. Masukkan menu entry puppy, kita misalkan file .iso puppy ada di partisi sda6, di folder Gukguk, ini contohnya:



#!/bin/sh
echo “add entry” >&2


exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the ‘exec tail’ line above.


cat << EOF


menuentry “Maverick – Live CD” {
loopback loop (hd0,6)/ihsan/ubuntu-10.10-desktop-i386.iso


linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/iso/ubuntu-10.10-desktop-i386.iso noprompt noeject
initrd (loop)/casper/initrd.lz
}


menuentry “Quirky 140 – Live CD” {
loopback loop (hd0,6)/Gukguk/qrky-140.iso
linux (loop)/vmlinuz
initrd (loop)/initrd.gz
}


menuentry “Puppy 520 – Live CD” {


loopback loop (hd0,6)/Gukguk/lupu-520.iso
linux (loop)/vmlinuz
initrd (loop)/initrd.gz
}


EOF




keterangan sda6 = (hd0,6)


3. Coba cek dulu /etc/default/grub, pastikan dikasih time out agar GRUB2-nya nongol


GRUB_TIMEOUT=10


buat nongolin menu entry GRUB2 selama 10 detik


4. Setelah selesai, ketik sudo update-grub
Reboot, insyaAlloh Puppy Live CD bisa muncul di pilihan…
