mkinitrd 4.x man page is missing instructions for loopback root
Last modified: 2007-11-30 17:10:54 EST
Description of problem:
The mkinitrd 3.x man page had the following paragraphs:
If the root device is on a loop device (such as /dev/loop0),
will build an initrd which sets up the loopback file properly.
this, the fstab must contain a comment of the form:
# LOOP0: /dev/hda1 vfat /linux/rootfs
LOOP0 must be the name of the loop device which needs to be
in all capital lettes. The parameters after the colon are the
which contains the filesystem with the loopback image on
filesystem which is on the device, and the full path to the
image. If the filesystem is modular, initrd will automatically
filesystemâs modules to the initrd image.
However, this is no longer mentioned in the mkinitrd 4.x man page. Was
this intentionally removed from the man page or is it just an
oversight? If the latter, then I believe the instructions should be
added back to the man page.
(The functionality still works; in fact, I'm filing this bug via a
router running Fedora Core 3 off a loopback file on a VFAT partition.)
Version-Release number of selected component (if applicable):
Loopback root stuff isn't officially supported any more. It might
still work but I don't ever test it and reserve the right to pull the
functionality at any time.
Documenting it is counter to that.
Ok, thanks for the explanation.
