3 more megs if we get rid of redundant copy of kernel?
by Douglas McClendon
It may well be that this has been discussed on this list before, and
worse yet, that I may have even participated, but if so I've long
forgotten, and it doesn't seem easy enough to search for.
In my livecd generation tools I go to a bit of extra hassle to play
symlink games with /boot/vmlinuz-$(uname -r), such that it doesn't get
put into the squashfs, since a copy of it is in the container iso/usb
filesystem.
Maybe we want to do that for f12? It is a bit messy, but I think it's
worth it for 3/700M.
peace...

persistence in Live USB
by Joseph Barney
I dunno if this is the right spot but had to try... I tried making a 2GB
persistence space on my Live USB... It's a fairly new 8GB Sandisk Cruzer,
and I've read that with fat32 you can make it as much as 4GB. I'm no
techical wizard, but more artsy but can usually manage on computers. I am
using Fedora 11. My system does boot off the flash drive but it gives me a
bit over 830mb of space, according to the OS but it is not
persistent...Anything saved is lost on reboot and I do have Fedora 11 on my
hard drive and installed it to flash with the official LiveUSB Creator. Any
advice? Thanks!

[ANNOUNCE] ZyX-LiveInstaller-0.1.1
by Douglas McClendon
A new GPLv3 - F11 compatible - _rebootless_ LiveOS installer is ready
for alpha testers.
Read all about it here, with full screenshot tour, src and binary rpms,
online browsable source tree, and beginnings of a FAQ.
http://viros.org/rebootless (redirects to:)
http://filteredperception.org/smiley/projects/zyx-rli/
All you should need to test out, is a system whose disk data you don't
care about, a stock f11 i686 livecd or liveusb, and an internet
connection. Boot up, fire up firefox, go to that url, install by
clicking the rpm link, and run the new desktop icon/launcher. If all
goes well, you should be able to eject the livecd or remove the liveusb
without powering down, and go about your business. Not to mention you
could have been going about your business while the install was
happening, and every change made to the filesystem even as you are
installing, gets live migrated to the target disk partitions.
Comments, feedback, bugs, and review will be greatly appreciated.
peace...

Don't continue if the fs unmount fails
We occasionally see something where the fs fails to unmount, but we
continue anyway. This then leads to weirdness. So just raise

Use resize2fs -M instead of binary search
esandeen got a "resize to minimal size" option added to resize2fs,
so we should use it rather than our bisecting down to a minimal
size. And maybe then we'll hit fewer resize2fs bugs.

Re: [Fedora-livecd-list] How to add icons to desktop for a custom remix
by Jane Dogalt
Actually, what you want to do is create a new file instead of appending to that one. That is one of those '.d' directories, where you can have lots of files, each one doing a specific thing. In this case, the liveinst one is owned by anaconda, and only meant to control the liveinst icon that gets added to the desktop. I'd go with >> zz-gamestuffs.sh or whatever. I assume the zz has something to do with being processed in alpha-sort order, so I'd keep that prefix.
