how to make freebsd run in RAM completely?

maitrikarunar · Oct 11, 2009

dear all,
i've been thinking what if freebsd can run in ram totally ? it will be awasome? do somenone know how to make it happens ?
My goals are
1. make freebsd mobile like puppy
2. make freebsd faster to load program
3. make freebsd runs totally in ram --> make the battery runs out very slowly
Other Question :
is ZFS is ready for daily use as official filesystem under freebsd ?

thanks....

Not sure about this one. Perhaps a LiveCD of some sort is what you're looking for.

ZFS is now ready for production use.

It's quite a long story but you should create an FreeBSD mfsroot image that contains the binaries needed to create a big memory disk, copy your system files to it and mount it on /

With some practice, yes. Familiarity with building world and kernel will help greatly.

All of them since 4.x I think...

Yup. I use it on a Soekris Net5501 here.

I just tried out Frenzy yesterday, and there is an option to run in RAM. Sadly, Frenzy 1.1 is the last release since the project has been discontinued.

After building world and kernel, is there any help already written to add packages nanobsd ? Downloaded packages into /usr/src/tools/tools/nanobsd/Pkg and using customize_cmd cust_pkg, the bootable image I got after running nanobsd.sh -c myconfigfile lacks /usr/local/bin in path, correct libraries versions for some packages, updated /etc/shells.

Somebody else took over the development of Frenzy. There is a frenzy 1.2 release. From the URL you posted

11.01.2010.
Frenzy 1.2 reincarnation (community release) is out. It's based on FreeBSD 8.0 and available in 2 versions: lite and standard.
This is a first version of Frenzy that's made not by me - author of this build is Egor Vershinin. You can read more on project's website (russian only).
English version of this build is avaliable on our FTP (lite and standard version).
