zfs discuss - Nov 2006 - shareiscsi supports breaks booting when a ZFS /usr filesystem is used

I''ve setup my opensolaris test box like this:

- Root: UFS
- /usr: ZFS
- /opt: ZFS

After bfu to opensolaris (2006-11-17), the system has become unbootable.
Solaris fails to mount the /usr filesystem at boot.

The "/sbin/mount /usr" commond fails with the error message

  ld.so.1: zfs: fatal: libxml2.so.2: open failed: No such file or directory

Same problem when running /etc/fs/zfs/mount.  Or /sbin/zfs.

It seems the new zfs shareiscsi support is responsible for this failure.

/sbin/zfs is linked against /lib/libzfs.so, which needs the new
/lib/libiscsitgt.so.1, which needs /usr/lib/libxml2.so.2, and libxml2
isn''t
available when we have a separate /usr filesystem.


libxml2.so.2 adds another dependency, libz.so.1


Workaround:  copy /usr/lib/libxml2.so.2 and  /usr/lib/libz.so.1 to /lib

I''ll need to check the exact date and bug number, but a fix has  
already been made which should take care of this problem. libzfs now  
dlopens the iSCSI target library when needed.

looks like this was noticed already; ahl put back:

6494840 libzfs should dlopen libiscsitgt rather than linking to it

on 11/17/2006
