USB key with overlay?

Hi all,

I don't find actually the answer on Arch wiki.
Creating an USB on arch is quite simple, but can we use with overlayfs to increase life of usb key ? Like live CDs ?

Thanks

Re: USB key with overlay?

Not exactly what you mean by "increase life".

If you mean "make good use of the remaining capacity for some sort of persistent storage", then look into:
https://wiki.archlinux.org/index.php/Mu … _USB_drive

If you mean "increase the size of the overlayfs", try for example

cow_spacesize=75%

the percentage is relative to your total RAM size. The default is 256M. FWIW, It is documented here:
