RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Fabian Deutsch 2015-02-19 10:11:43 UTC 
To boot live images without a disk (diskless boot, in this sense also stateless), rd.live.fsimg can be used.
Currently that directive takes a compressed archive containing a filesystem image.
But often squashfs images containing the rootfs image are provided.

This feature request is about enabling rd.live.fsimg to use squashfs images as well, this allows us to reuse the squashfs image which is already used by anaconda for installation.
Comment 1 Fabian Deutsch 2015-02-19 10:12:15 UTC 
This feature got implemented with
https://github.com/haraldh/dracut/commit/b0472eac111268e2cae783097d0eccc1986e1762
Comment 4 Fabian Deutsch 2015-09-15 12:47:40 UTC 
This feature can be tested by:

1. Get the squashfs.img from a livecd to some http server
2. Somehow boot with a kernel and a dracut image containing this fix
2. Modify boot param to use the following boot arguments:
root=live:http://path/to/squashfs.img rd.live.fsimg=1
3. After boot check that /run/initramfs/fsimg/ exists

well, there is no rd.live.fsimg in dracut code. maybe in anaconda?

The directory is only created, if "rd.writable.fsimg" is specified on the kernel cmdline.
Comment 7 Fabian Deutsch 2015-09-24 12:15:11 UTC 
Indeed. My memory was bad.

it should be as in comment 4, but using rd.writable.fsimg instead of rd.live.fsimg
