SUMMARY: Help: Some how have lost /usr/lib/libc.so.1 (fwd)

Thank-you for all who responsed.
Too many to name all. This is a fantastic list (but it took 2 days
for my original e-mail to appear :(  )

Here is a cut and paste of one of the e-mail

1.  Boot from cd into single user.

2. fsck /dev/rdsk/c-whatever is you rootdisk

3. mount rootdisk as /mnt

4. cd /mnt and then do your restore.

	. ftp/copy over from another system in the same subnet
		"remember u should copy from the same version of OS"
	. tape backup
	. mount the root fs on /a; the /usr on /a/usr and
	  use pkgadd -R /a -d <packages source directory> SUNWcsl



This should work ok to restore /usr -

And for those who have the root disks encapsulated with Veritas or DiskSuite
	"Just you hope you haven't"
I guess this means a re-install of the OS.

   Its actually zero'd:

      # ls -l /a//usr/lib/libc.so.1
      -rwxr-xr-x   1 root     bin            0 Apr 30 23:52
   /a//usr/lib/libc.so.1

   And of course I cannot boot - can anyone tell me how I can
   restore this file in single user mode . The text below show
   the output when I attempted to boot my box:
