: Hi,
:
: I am looking for mini freebsd customized OS (less than 50MB). Is it
: possible to customize the freebsd to below 50MB?
:
: The list of modules i run over freebsd OS
: 1. TCP/IP stack
: 2. package installation.
: 3. File read and write operation
: 4. Apache server
Web server, you mean? Apache and small aren't mates.
: What is the minimum size of the stripped freebsd OS ?
I've booted a minimal FreeBSD/arm ramdisk that fits in a 8MB flash
part. I have a fuller FreeBSD/arm system that's 42MB (uncompressed),
including a 15MB JRE/web tools, approx 6MB of snmp support code, and
~4MB of application code. The minimal system is like 16MB (numbers
rounded). This includes thttpd, which supports many of the things
apache does, but is much smaller.
For a different product, I have a 13MB FreeBSD/i386 base with 2MB of
application code.
: Please let me know detail/link how to customize freebsd OS.
I'd use the tinybsd tools in FreeBSD. We did this with a customized
set of build tools that we've been using since before there was a
tinybsd...
