linux - How to boot from SSD but have installations and home folder on HDD


I have an SSD I want to boot from it, but use the HDD to store installed programs and keep the home folder.


I'm running Linux Fedora 19.


How do I set that up?



Answer



During installation you will be asked which disk to use and which partitions to mount. Reading you question I think you want this:


[SSD]
/boot
/
SWAP


[HDD]
/usr
/tmp
/home

Why this?


[SSD]



  • /boot from the SSD (not much here, /boot is only a very small filesystem needed to start and optionally to decrypt a volume.

  • / on the SSD since you will be accessing it quite often en thus gain a large speed gain. / (the root filesystem) is usually quite small and it is here where you usually have the mount points for other filesystems such as /usr, /usr/local, /opt, /var, /lib etc. Some of these you want to keep on /, such as var and lib. Others such as /usr/, /usr/local/ and /home are best mounted from another partition.

  • SWAP since paging depends a lot on the disk speed. Thus is gains the most from the SSD. And with modern SSD there is no reason not to do this. A modern SSD (read: any SSD manufactured in the last decade) can sustain heavy writes for years. Your computer will be old and discarded before you reach this limit).


[HDD]



  • /usr on the HDD since you ask to use the HDD for the programs. Most of these are stored in /usr (OS/distribution provided) or in /usr/local (self installed).

  • /home for the same reason.

  • /tmp is a choice. If you have sufficient memory then /tmp in RAM makes a lot of sense. If you use it to also store temporary ISOs etc then using a partition makes more sense.

keyboard - Is there any utility/method to change Windows key bindings to type rare chars to currently empty bindings?

I'm currently typing this post with my windows XP machine and (Spanish) keyboard, and I'd like to add some extra symbols to my text. I could open the "char map" windows utility, look for the desired symbols, and paste them. But I'd like something quickier. For example, when I'm using my OSX Mac at work, I can easily add a ©, ™, ® or similar symbols, just pressing some weird ALT-GR + G / H / J, key combinations. In my (Spanish) keyboard mapping, these combinations are empty, as they don't produce any char at all, which, on the other hand, is perfectly normal and desirable. So, I thought: Why couldn't I add some extra key mappings on top of my currently empty ALT-GR + G/J/H Keys in my Spanish keyboard, and thus, being able to quickly type these special symbols? So that's my question: Is there any utility/method to achieve that effect under windows? (My version is XP). I've even googled this for some time but no luck. I've been a long term Hot...

macos - Visit URL in running Firefox instance from command line in OS X

I have Firefox 3.6 installed on my OS X (10.6) box. I would like to open an URL in the running Firefox instance (in a new tab or window, no matter) from the command line. I tried several ways, neither switches -new-tab , -new-window , -url , or none helped me. I always get the A copy of Firefox is already open. Only one copy of Firefox can be open at a time. error message. Answer running open http://www.superuser.com from the command line will (at least for me) open a new tab to superuser.com in firefox (which is my default browser)

virtualization - How to select paravirtualization interface in VirtualBox?

Given a windows 8 host system (Intel Core i5) and a Linux Fedora host, I would like to determine the optimal setting for the paravirtual interface. Options are none Default Legacy minimal Hyper-V KVM This page suggest the selection is only based on the guest system: The biggest change in VirtualBox 5.0 is the introduction of paravirtualization support, bringing higher performance and time-keeping accuracy to supported guest operating systems (Hyper-V on Windows and KVM on Linux). Is that correct? Answer The VirtualBox Manual , in the section titled Paravirtualization providers explains very clearly when each should be used (emphasis added): Minimal: Announces the presence of a virtualized environment. Additionally, reports the TSC and APIC frequency to the guest operating system. This provider is mandatory for running any Mac OS X guests. KVM: Presents a Linux KVM hypervisor interface which is recognized by Linux kernels starting with version 2.6.25. VirtualBox's implementati...

How can I migrate a Windows 10 from BIOS/MBR boot to UEFI/GPT without reinstalling?

I've installed Windows 10 in BIOS mode and use MBR. How can I convert it to use UEFI and GPT without reinstalling Windows 10? Is this possible? Answer In Windows 10 v1703 (Creators Update, Build 15063), there is a tool called MBR2GPT.EXE included which does all steps . Best is to boot from a Win10 v1703 DVD/USB drive to the repair option (WinPE) and run Command prompt (cmd.exe) under repair options . Now use diskpart and list command to see all drives. X:\>diskpart Microsoft DiskPart version 10.0.15063.0 Copyright (C) Microsoft Corporation. On computer: Win10v1703 DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 60 GB 0 B Now look or the disk number where your Windows is installed. This number is important for next step. Now run mbr2gpt /convert /disk:ID with the ID: X:\>mbr2gpt /convert /disk:0 MBR2GPT will now attempt to convert disk 0. If conversion is s...
