[PATCH 6/7] rename ext3fs.img to ext3.img for consistency

by Douglas McClendon

This patch renames the ext3fs.img file to ext3.img, to conform to a syntax of <fstype>.img, along with the existing squashfs.img. This may be useful for future code simplification. I like it. -dmc

[PATCH 5/7] rename os.img to ext3fs.img for consistency

by Douglas McClendon

This patch renames os.img in the embedded squashfs.img to ext3fs.img, to be consistent with the name choice of ext3fs.img in the --skip-compression case. -dmc

[PATCH 3/7] move embedded fs image under /LiveOS for consistency

by Douglas McClendon

This patch moves the /os.img that is embedded in a squashfs to /LiveOS/os.img, to be consistent with non-embedded location. I find this aesthetically pleasing, and suspect that it may facilitate more elegant code in the future. And I see no downside. -dmc

[PATCH 2/7] move livecd fs image under /LiveOS, like liveusb already is

by Douglas McClendon

This patch makes the livecd filesystem layout match the layout that currently gets put on liveusb via livecd-iso-to-disk. Namely, /squashfs.img or /ext3fs.img and /osmin.gz get put under /LiveOS/ -dmc

[PATCH] disable mksquashfs progress bar for non-interactive sessions

by Douglas McClendon

This patch introduces a global variable 'interactive' which is defined as true if stdout of livecd-creator is attached to a tty. This global is then used to add the -no-progress option to mksquashfs for non-interactive sessions. Thus making logfiles created by redirecting the output of livecd-creator, reasonably readable (e.g. with less). This may or may not solve the root issue that Jon Steer recently brought up. (maybe he wants it disabled even in terminal situation, in which case a --verbose/--debug/--quiet infrastructure is called for, which IMO would be a great addition as well). This specific case, might also be better as an upstream mksquashfs modification (Phillip, should I submit a patch?), but I think the global is handy, for instance if we want to provide our own progress bar. Comments welcome on generic style issues as always (is there something preferable to a global in this instance?) -dmc

[PATCH] squash osmin: saves 1.2MB of ram during LiveOS session (except install)

by Douglas McClendon

The attached patch implements the solution recently discussed, to avoid wasting 1.2M of ram during LiveOS sessions, during the non-install times when the 1.2M of ram for the minimized filesystem overlay is not actually needed. This implementation involves putting osmin in its own squashfs, and copying that 12kb image to ram, as opposed to an alternative of putting osmin in the same squashfs as the main system image. I chose to implement the seperate version, because it guarantees that the install will remain one long ~2G seekless cdrom read. This is seperate from the filesystem layout patchset I posted, but straightforward merging would need to be done if they are both applied.

[PATCH 2/2] allow user specifiable number of loop devices

by Douglas McClendon

Jeremy recently committed a patch which changed the number of loop devices created from 128 to 16. I don't know if there was some measurable performance reason for this or not. I had always guessed that the reason David chose such a large number originally was because of the fact that unlike in a normal system, in a LiveOS system, a loop device is used for the rootfs, and therefore the loop driver can never be removed and readded with a larger number of devices if needed. This patch adds an optional kernel commandline parameter num_loopdevs=<int> which will cause that many loop devices to be created instead of the default of 16. This will be useful for people using the livecd who need lots of loop devices, but doesn't interfere with whatever reasons justified the lowering from 128 to 16. If you want to add this functionality without the prior patch which removed the while-wait, somthing like- maxloopdev="/dev/loop\$((\$num_loopdevs - 1))" while [ ! -b \$maxloopdev ] ; do sleep 1 done should do the trick -dmc

[PATCH 1/2] move loop modprobe before udevsettle, for simpler code

by Douglas McClendon

The attached patch moves the loop modprobe call in mayflower generated init, to before the udevsettle call. Thus also removing the while-wait loop that Jeremy wisely added to my dynamic loop device patch. Theoretically, one could argue that the while-wait loop is still needed, as the udevsettle command is allowed to fail. I would personally feel comfortable committing this without the while-wait loop, because it seems like if udevsettle fails with a timeout of 30, it will never(tm) be because the loop devices have not been created. -dmc

RFC- proposal for livecd filesystem layout changes

by Douglas McClendon

This is a (set of) proposal(s) that I don't feel too strongly about, but if people agree, I wouldn't mind implementing. First, I'd like to put together and submit a patch, that moves the placement of /squashfs.img in the livecd iso to /LiveOS/squashfs.img This would have the benefit of cleaning up some code that differentiates between that placement on live-usb, and the current /squashfs.img on current live-isos. Another benefit is making the iso directory structure look nicer and more intuitively understandable for someone looking at it under windows. A downside, is that an F7 version of livecd-iso-to-disk would not work with an F8 livecd. I think its worth it, but I admit it is a downside. Also, livecd-iso-to-disk would look a bit uglier, if it needed to maintain the ability to support livecds made with the current scheme. Along the same lines, I also suggest moving /isolinux(livecd) and /syslinux(liveusb) to /boot/isolinux and /boot/syslinux. This also would make the usb/iso directory structure look cleaner and more intuitively understandable to less linux-guru users when they look at the directory structure under windows (or anywhere) And because it is somewhat on-topic, I would also suggest changing the current squashfs.img:/os.img to be squashfs.img:/ext3fs.img, as that would be consistent with what it is named in the --skip-compression case. Also, I would modify the above to be ext3.img instead of ext3fs.img, such that the naming convention is consistent with squashfs.img (i.e. name of filesystem as passed to mount -t). Finally, I would suggest changing squashfs.img:/ext3.img to squashfs.img:/LiveOS/ext3.img, such that the general idea is that a container filesystem such as squashfs presents the result in the same place you would look for it without the extra container filesystem. $0.02... -dmc
