[solved:] Dynamic root filesystem remastering: max initramfs size

[slo.sleuth]

Does anyone know the maximum size of initramfs allowed by syslinux?  I am attempting a Dynamic remaster of TC as suggested in the wiki at http://wiki.tinycorelinux.com/Dynamic+root+filesystem+remastering.  I don't find the limitation listed in the syslinux wiki.

I tried booting with an 82mb initramfs and booting failed, complaining it was too big.  Alternatively, I could make several initramfs files if I knew how small to make them.

According to H. Peter Avin there is no such limitation by syslinux per se.
He recommends to:

a) report the output from meminfo.c32;
b) try using linux.c32 to run the kernel

b) is because linux.c32 is smarter about where it puts things than the core kernel loader; it's actually a standalone preview of the next generation Syslinux code

Yes, I found that, thank you.  Turns out, I'm a knucklehead!  Sometimes it just takes an embarrassing post to remind one of that fact.  

I was testing in qemu, and forgot to change the default ram from 128mb.  It booted fine when I increased the memory.

So, in case someone stumbles on this thread: Check to see that you have sufficient ram to load the initramfs if you receive the "initrd too large" syslinux error on boot.

You could have mentioned something that this was about emulation, plus you neither opened the thread in the specific subforum for such, but in "TCB Q&A Forum".
 
Knowing that could easily have led someone to suspect a virtual mem limit.
