Hi,

In diskless mode total amount of RAM is equally split between / and
/dev/shm. How do I increase size of / and reduce size of /dev/shm?

Hi,

Maybe `mount -o remount,size=2G /`?

You increase the size of / with the boot option `rootflags=size=...`

For /dev/shm, I'm not sure.

Thanks. Both methods works. To achieve what I want, one can add this to
fstab:

tmpfs    /           tmpfs    size=90%                        0 0
tmpfs    /dev/shm    tmpfs    size=10%,nosuid,nodev,noexec    0 0
