Re: mount shows dm-* instead og dev/mapper/*



Hello,
I forgot to give my conf.
I run a fully updated fedora 10

[root jack ~]# uname -a
Linux jack.lutty.net 2.6.27.24-170.2.68.fc10.i686 #1 SMP Wed May 20
23:10:16 EDT 2009 i686 i686 i386 GNU/Linu

If nobody has a clue about that, I will bug Zilla, probably under
device-mapper-1.02.27-7.fc10.i386

regards,
laurent
