[Umlbuilder-devel] UML Builder 1.0 out

[Roger B. <ro...@ro...>]

I have released UML Builder 1.0.  There are no functional changes since 0.9-3
and it works well.

I have also started work on a different user interface.  This is to allow the
configuration of more settings, without annoying every user with the minute
detail.

A derived interface will also be used to allow changing many settings after
you have created a guest instance.

If you install 1.0, run umlbuilder_gui_v2demo to see what it will look like.

[Umlbuilder-devel] What I am working on next

[Roger B. <ro...@ro...>]

I am going to make UB create a file called settings in
the install directory.  This will contain all the settings
for the session and will be sourceable by the control script.

The control script will then effectively become read only
since you'll only ever need to change things in the settings
file.

The second step is a graphical control program which will
effectively edit the settings file.  (Power users can use
vi :-)

This will allow easy adding/removing of filesystems, having
undoable disks, resizing memory/swap etc.

The reason is because the standard UML rpm that Jeff distributes
has reiserfs as a module.  The modules reside on the root filesystem
(under /lib/modules) and root can't be mounted.

If you build UML yourself, then you can include reiserfs as a builtin
so this situation won't arise.

UML Builder does in fact create an initrd.  The main problem is that
I don't know how to use this.  Some distributions (eg Caldera) don't
include the mkinitrd program either.

[Umlbuilder-devel] Reiserfs on /

[Jonathan R. <mma...@ya...>]

Roger,

I noticed that one of UML Builder's know problems was that reiserfs
doesn't work on / and you are talking about the need to use an initrd to
solve this.  There shouldn't be any need for this.  I've been successfully
creating reiserfs on root for a long time.  The only thing to watch out
for is that the fs is > than a certain size, I think it is 30M or
something, this is because it is a journaling fs and it requires some
space for that journal.  You may want experiment with gbootroot to
discover the required size, I think this is probably the cause of this
problem. 

Regards,


Jonathan
