Bug 218928

Description of problem:

With an iscsi root filesystem (manually configured via mke2fs, tar, --bind
mounts, and chroot), mkinitrd fails because it tries to pass a "-M sysdir"
option to iscsiadm that is not accepted.

Version-Release number of selected component (if applicable): 
mkinitrd-5.1.19-1
iscsi-initiator-utils-6.2.0.747-0.0.fc6

How reproducible:

Every time.

Steps to Reproduce:
1. have a root (/) filesystem mounted from an iscsi device
2. run mkinitrd to generate a new image with iscsi root boot support
  
Actual results:

% mkinitrd -v initrd-2.6.18-1.2849.fc6iscsi.img 2.6.18-1.2849.fc6
...
setting iscsi parameters
/sbin/iscsiadm: invalid option -- M
iscsiadm: unrecognized character 'M'
Unable to find iscsi record for
/sys/devices/platform/host15/session0/target15:0:0/15:0:0:0


Expected results:

A successfully created image. When I manually hacked a copy of mkinitrd
to pass -T <target> -p <portal IP> instead of the "-M $1" arguments
in iscsi_get_rec_val, it seems to generate an initial ramdisk successfully.

Additional info:

I notice that the manpage and brief help for iscsiadm list the -M sysdir
option but it is not included in the detailed explanations later in the
document. Has this option been deprecated or otherwise disabled?

Here is a full output of mkinitrd when it fails:
