Live USB filesystem is too small

[samsheff]

I have been using penguins eggs to make a live usb stick for several months, and recently after updating, when I boot the usb, the os only has about 150mb of free space on the in-memory filesystem. It makes it impossible to use the live OS because not everything can be moved to a mount point, and some things will still write to the ramdisk. And once it runs out of space I need to reboot.

Did something update that made the live disk smaller? I havent been able to figure out what it is if I broke something on my end, but this looks like some configuration change in eggs.

Any idea what this could be?

One more piece of info - The OS im building on is Arch.

The time you tell is long enought to try to imagine the problem...

• first passing from 9 to 10 I started to use nodejs from the distro in Debian, Arch remain more or less the same, but share the same codebase;
• lately, becouse I saw with openSuSE syslinux 6.04 original work - for me - better than the original, I investigate for the others distro. This end to put syslinux inside eggs and remove the syslinux dependecies:
• another idea, the way actually we compress the disk, using zstd in the place of xz. You can try to set the option --max, to work in the old style;
• in same places there is a parameter to decide the size of the in memory system... I must to look don't remember where I saw, but perhaps on archiso disk.

Let me try --max and see if that helps. If not, maybe I can help with the memory size parameter. Im sure its configurable, just need to find where.

If its the solution and I can find it I will open a PR.

[samsheff]

Just checked my build command, it already uses --max. So thats not the solution.

What part of the code creates the RAM disk? I can look into it

A possible work around is to use Ventoy with Persistence Plugin

[samsheff]

Ventoy looks interesting, but I would much rather use this project if I can. Ive been using it for almost a year, and this bug was only added recently, in the last month or so. What version can I roll back to where Arch would be better supported?

Hey @pieroproietti

What is the name of the command that creates the ramdisk? Tried Ventoy with the persistence plugin, still only shows 150mb of space. How can I help you get this fixed?

[samsheff]

@pieroproietti The suggestion in the stack overflow solved it: https://superuser.com/q/753134

By adding cow_spacesize=2G to the grub boot options it will increase the size. How can we add this to the build? I will submit a PR.
