From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Is it ok to split home on another drive? (lemmy.world)

Hey folks. I recently got an old X220 with an mSATA SSD. I plan to to install Linux on there. It doesnt matter which OS: Debian, Ubuntu or Arch. The machine is so old that all distros play nice with it.

Anyway, the speed on the mSATA is slower than the 2.5 SSD. So I want to know if is it possible to have your /boot, /efi, swap on the mSATA. Then, the /home on the 2.5 SSD? Any problems with this setup and if anyone tried it before?

Now, for the reasons why I use mSATA instead of just putting Linux on 2.5 SSD:

the mSATA is Samsung, pretty rare nowadays. The health is still very excellent. I checked with CrystalDiskInfo. So might as well use it.
My X220 has a problem finding out grub if installed on the 2.5 SSD. It's literally a 50/50 chance it can find grub properly. So:

a) you installed Linux on 2.5 SSD, reboot.

b) grub error screen

c) restart

d) boot into Linux well

Note at d) if I do anything to restart/shutdown the computer, you are back at step b) and require another reboot to reach Linux.

Any advice is welcome.

Ha, home has been traditionally always on a separate drive. That's the reason why root user has the home under /root and not /home/root, so that it can login even if the home drive didn't Mount.

As a curiosity, even /usr was traditionally on a separate drive and that's why critical binaries and libraries where under /bin and /lib while all non critical stuff under /usr. It is called "split-usr".

Nowadays /usr is always on the same drive as root, and we moved to a "merge-usr" approach where stuff under /lib and /bin is a symlink into /usr/lib and /usr/bin.

Because when HDDs where 50mb in size, even that small binary file counted as big :)
