Hello,

How can we create a live CD containing files which are not in a RPM?
More specifically, I need to create a live CD containing tomcat and a
custom web application(jsp). The custom web application is in war
format. Is it possible to do it without creating a rpm for the custom
app?

Regards,

Parminder S. Lehal

Some syslinux versions have this bug.  I don't remember when it was
introduced, but based on looking at the changelog, I fixed it in 3.36-3.
The fix should be able to be applied to any earlier version with the
problem as well IIRC

Thanks Matt; applied.

Attached is a _first pass_ patch that enables LiveOS persistence for 
livecd-tools.  Before you read this and get _too_ excited, note that I'm
really 
only posting this because of the f8t1 devel freeze.  If I get any
encouragement, 
I am very willing to work my ass off in the next few days to get this
cleaned up 
into respectable shape for a potential f8t1 feature.  But I also realize
it is 
probably just too late for that. (OTOH the code is already structured so
that it 
is obvious that in the absence of a persistence bootarg, the code has no
impact)

The Principals Of OPeration are-

- unless a boot argument of "persistence[=[devspec][:pathspec]]" is
seen, 
nothing will behave differently, except for the existence of a new tool 
/usr/sbin/livetool

- after booting normally (no persistence bootarg), if you invoke

"/usr/sbin/livetool persistence initialize [devspec][:pathspec]"

then a persistence file will be initialized.  By tomorrow I should have
an 
option that allows the existing in-ram-overlay to be live migrated to
the new 
file (thus freeing the ram by the time the command completes).  I have
done this 
manually.  Currently this tool is not implemented.  Creating a sparse or
zeros 
file of any size (say 512M) should work fine.

e.g. dd if=/dev/zero of=/mnt/stick/LiveOS/Persistence-mylabel \
bs=1k count=1 seek=$(( 1024 * 512)

- to use the persistence file on a subsequent boot, add the bootarg 
"persistence" which is equivalent to "persistence=auto"

- devspec can be in the following forms (should be obvious what they
mean),
and defaults to auto, which means to search all mountable partitions.
(the 
search process mounts readonly (with paranoid blockdev --setro as well)

sda1
sdb
/dev/sdc3
LABEL=MyLabel
UUID=MyUUID

- pathspec defaults to /LiveOS/Persistence-LIVEOS_LABEL
(e.g. /LiveOS/Persistence-Fedora-7-Live-i386)

if pathspec does not start with a /, it prepends the above default.
(e.g. persistence=:dmc would mean to search all partitions for 
/LiveOS/Persistence-Fedora-7-Live-i386-dmc)

if pathspec starts with a / then it is used as is.  e.g. 
persistence=:/home/dmc/testpers would search all partitions(and whole
devices) 
for /home/dmc/testpers )

To round out the examples, persistence=LABEL="my usb
stick":/my/path/to/file

Finally: Known bugs:

1) I had to comment out the mayflower generated init's trap and set -e

2) ext3's inability to mounted readonly is annoying (yeah, I know
norecovery or 
ext2 will probably get it for me, still annoying)

3) choice handling is broken.  Don't use auto when it will find more
than one 
entry.  Maybe just don't use auto at all.

4) livetool doesn't do anything.  For now, just create a sparse file of
any 
interesting length (512M is fine) as mentioned above.

Well, that about covers it for now.  As always, comments, suggestions,
and 
criticisms will be greatly appreciated.  (though feel free to wait 48
hours for 
plenty of obvious improvements, such as fixing those known bugs).

"release early, release often"...

I mentioned in a prior mail that I'm a bit annoyed by this as well.  I may whip 
up a simple patch allowing args to livecd-creator to throw in extra directories.

For now, I think the best way is to use the --shell option, and then do 
something like 'ls -altr /var/tmp/livecd-creator*' to find the installation root 
to copy your files into.  But NOTE- you would have to do this in ANOTHER 
terminal, because in the shell livecd-creator gives you, you are stuck in the 
chroot.

I haven't tested the above, but I think it should work.

You can also grab things in your config's %post section.  That's what
I've done in the past to accomplish this.  I stuck files up on a
webserver and just grabbed them with wget

You could use the copy_dir and strip_copy_dir configuration directives 
in Revisor, too.
