[linux-lvm] system-config-lvm bug with using lv as swap space

[wu jessinay]

Hello jim
I have created a bugzilla with my patch attached.
the bug no is 475434.

Another thing I'd like to know is that if you have plan
to enhance system-config-lvm with more functions.
Such as add swap entries to /etc/fstab and create swap
partition on a lv

Thanks
