### Debian GNU/Linux with read only root filesystem.
|
||
|
|
|
||
|
|
* Example:
|
||
|
|
/dev/sda: SSD disk (solid state disk)
|
||
|
|
/dev/sdb: HDD disk (mechanical disk)
|
||
|
|
|
||
|
|
/dev/sda1: /
|
||
|
|
/dev/sdb1: swap
|
||
|
|
/dev/sdb2: /home /tmp /var/tmp
|
||
|
|
|
||
|
|
* Install Debian in /dev/sda1
|
||
|
|
|
||
|
|
* Boot Debian in /dev/sda1
|
||
|
|
|
||
|
|
* Update & upgrade
|
||
|
|
apt-get update
|
||
|
|
apt-get dist-upgrade
|
||
|
|
|
||
|
|
* Mount HDD disk
|
||
|
|
mount /dev/sdb2 /mnt
|
||
|
|
|
||
|
|
* Make /tmp directory
|
||
|
|
mkdir /mnt/tmp
|
||
|
|
chmod 1777 /mnt/tmp
|
||
|
|
chown 0.0 /mnt/tmp
|
||
|
|
|
||
|
|
* If needed, copy all users data from SSD to HDD
|
||
|
|
rsync -av /home/ /mnt/
|
||
|
|
rm -fr /home/* ; rm -fr /home/.* <-- CAUTION!
|
||
|
|
|
||
|
|
* Get the UUID of the partitions
|
||
|
|
Example:
|
||
|
|
blkid
|
||
|
|
/dev/sda1: UUID="505267d4-ad80-4eae-b6ed-ebfec59e4748" TYPE="ext4" PARTUUID="60a30271-01"
|
||
|
|
/dev/sdb1: UUID="6b684928-5786-4882-af6d-b9d8c98bccf0" TYPE="swap" PARTUUID="5e1c8d9b-01"
|
||
|
|
/dev/sdb2: UUID="30e81e2b-faaa-43a4-b188-db37c13588a6" TYPE="ext4" PARTUUID="5e1c8d9b-02"
|
||
|
|
|
||
|
|
* Edit /etc/fstab
|
||
|
|

|
||
|
|
UUID=30e81e2b-faaa-43a4-b188-db37c13588a6 /home ext4 noatime,errors=remount-ro,x-systemd.requires=/ 0 1
|
||
|
|
UUID=6b684928-5786-4882-af6d-b9d8c98bccf0 none swap sw 0 0
|
||
|
|
/home/tmp /tmp none bind,x-systemd.requires=/home 0 0
|
||
|
|
/home/tmp /var/tmp none bind,x-systemd.requires=/home 0 0
|
||
|
|
|
||

* For optional NFS server, add in /etc/fstab
|
||
|
|
