Description Bastien Nocera 2006-03-23 12:04:58 UTC 
1. Start the installation with dd=http://path/to/vfat-dd.img
vfat-dd.img being a VFAT driver disk
2. Error out with "Invalid argument"

The current HEAD code tries to mount loopback images as vfat in mountLoopback(),
but the RHEL3 code doesn't.

HEAD:
    /* FIXME: really, mountLoopback() should take a list of "valid"
    * filesystems for the specific type of image being mounted */
   if (doPwMount(filename, mntpoint, "iso9660", IMOUNT_RDONLY, NULL)) {
       if (doPwMount(filename, mntpoint, "ext2", IMOUNT_RDONLY, NULL)) {
           if (doPwMount(filename, mntpoint, "cramfs", IMOUNT_RDONLY, NULL)) {
             if (doPwMount(filename, mntpoint, "vfat", IMOUNT_RDONLY, NULL)) {

RHEL3:
    if (doPwMount(filename, mntpoint, "iso9660", 1,
                 0, NULL, NULL, 0)) {
       if (doPwMount(filename, mntpoint, "ext2", 1,
                     0, NULL, NULL, 0)) {
           if (doPwMount(filename, mntpoint, "cramfs", 1,
                         0, NULL, NULL, 0)) {
               logMessage("failed to mount loop: %s",
                          strerror(errno));

Patch attached.

Created attachment 126537 [details]
anaconda-try-vfat-for-dd.patch
Comment 2 Bastien Nocera 2006-03-23 12:06:50 UTC 
Note that having the image on a local device such as a floppy instead will mount
the floppy as vfat successfully.
Comment 5 Bob Johnson 2006-04-11 16:16:58 UTC 
This issue is on Red Hat Engineering's list of planned work items 
for the upcoming Red Hat Enterprise Linux 3.8 release.  Engineering 
resources have been assigned and barring unforeseen circumstances, Red 
Hat intends to include this item in the 3.8 release.
