Ubuntu on a USB stick - mount options to reduce writes

Solution 1:

I have made a lot of installed systems into USB flash drives, and I think such systems can work quite well. You have found some mount options, that I have not found (and not used). I am looking forward to future reports from you :-)

See this link about my systems, and the tweaks that I suggest,

I think it is important to get a fast USB 3 flash drive (and I think there are better drives for this purpose than the Ultra Fit),

help.ubuntu.com/community/Installation/FromUSBStick#Notes_about_speed

I think that the lifetime of good USB pendrives is rather good now, but still, it is important to backup all important files at regular intervals.

An alternative is a persistent live drive with a casper-rw partiiton, and if you wish you can add a home-rw partition,

A persistent live drive is more portable, but cannot be updated and upgraded like an installed system (the kernel and drivers cannot be upgraded). But an installed system is often portable enough.
