[User-mode-linux-devel] New build script

[William S. <wst...@po...>]

Good day, all,
	For once, I'm actually _contributing_ something!  *grin*
	Jeff had asked a while back if I could do some work on root
filesystems for different distributions; as part of the uml work I'm
doing, the replacement build script just naturally handles them.
	I've attached the build script and support function file.  One of
the major changes is the use of "addline", "delline" and "substline",
which respectively add a line to a file, remove a line from a file, and
substitute one string for another in a file.  These three functions allow
me to make all the changes that were originally done by Jeff's
initfiles.tar, but allow me to do it in a distribution-independent
way.  In other words, If I know that /dev/tty0 needs to be changed to
/dev/ttys/0 in rc.sysinit, I can tell the build script to make this one
change, instead of having to include a complete replacement rc.sysint to
overwrite what might be a completely different rc.sysinit in a new
distribution.
	If all the RPMS= lines are uncommented, it seems to be doing
pretty well at running servers, running jleu's ethernet, and even running
X (get networking going, run "xhost +uml_ip_address" on the host, and run
telinit 3 in uml).  The X tends to be pretty flaky - it just segfaults
every 30 seconds to 3 minutes, depending on load - but it does generally
function.
	Jeff, could you take a look at this and offer suggestions?  I'd
really like to make this general enough that it could build any RPM-based
distribution.  If you have other mkrootfs scripts that you use to make
other rpm root filesystems, could you email them to me so I can integrate
them?
	Constructive criticism, suggestions, and patches are welcome from
anyone, of course!
	Cheers,
	- Bill
