Re: [K12OSN] How to update K12LTSP-5.0.0EL-32bit chroot

I'm a little late to the party here, and not to dissuade your work here...

The LTSP5 setup used in the F10 K12Linux chroot is wildly different
than that of the LTSP4.2 setup used in K12LTSP5.0.0EL, thus it's
likely to be an uphill battle to make the chroot from one work with
the other. The LTSP5 chroots are built at install-time from the
hosting operating system, LTSP4 distributed an entire self-contained
chroot environment.

A comparison of LTSP4.2 and LTSP5:

I found the old LTSP4.2 era wiki archived here:
