[Dump-devel] sparc vs x86 info/dumps etc....

[Rob C. <ce...@Ru...>]

Dumps from dumpe2fs, the file systems are the same type and block size,
groupings are a bit different.  See information below.

I created a directory with a file in it...

x86:
[root@njlug /root]# ls -l sparc
total 4
-rw-r--r--   1 root     root         3782 Feb  8 15:38 rpm.list

sparc:
[root@bismark /root]# ls -l sparc
total 4
-rw-r--r--   1 root     root         3782 Feb  8 14:46 rpm.list

Right from the get-go the simple command dump 0S sparc on both
systems produce differnet results:

x86:
[root@njlug /root]# dump 0S sparc
49152

sparc:
[root@bismark /root]# dump 0S sparc
70656

I'll put the two tapedumps on the website with the sparc RPMs.
   tapefile.sparc  [dump 0f tapefile.sparc sparc]
   tapefile.x86    [dump 0f tapefile.x86 sparc]

[Do you have the Commercial version of secureshell installed 2.0.13?
  If so, I can give you access to a 'SparcLinux' box...just send me a
  public key and we can go from there.
