Re: [Trinux-talk] RAM adjustment...

[Matthew F. <mf...@ci...>]

The quick answer (and I'll have to revisit the linuxrc for a longer
answer, since it has been a while) is that /dev/ram will be set by the
size of the initrd.

See http://www.io.com/~mdfranz/trinux/devtools/mkrd
for how the initrd is built. Specificially the count for dd sets the
size of the ramdisk.

There also a hard kernel limit on the size of the ramdisk that you can
configure when you build the kernel. It is likely that it is set at
8mb/16mb.

However you should be able to get around this by creating a huge /usr
partiion and configuring the size of the partition either within the
linuxrc, since ramdisks aren't used for none / partition. tmpfs
/dev/shm is used.

Search for tmpfs or none or SIZE or even mkfs.minix and you should see
where they are created.

- mdf
