How do you make rootfs bigger?

[joeinwap]

Right now, Linux does not get fully started.  UDEV complains about no space on the device.

This is after installing Perl and Chromium on a 256MB laptop.  (t is certified for Windows 2000 Pro.)  I thought a reboot would make it recalculate the appropriate size for rootfs, but alas.)

I fear that I will have to redo the full install, do something to increase rootfs, and reboot.  But I don't know how to do that.

What you need is persistence, Instead of modifying rootfs(core.gz/ corepure64.gz), which is explained in detail in the link below.

It sounds like you installed them copy2fs, in RAM. That's a bad idea when you don't have much RAM.
