Is there a way to check to see if your 'swap is on' (gui and cli)in
other distros, like Suse 10.1? I see the swap in my /etc/fstab but not
when I df -h.
like this:
linux-28:/ # cat /etc/fstab
/dev/sda7            /                    ext3       acl,user_xattr
   1 1
/dev/sda6            /home                ext3       acl,user_xattr
   1 2
/dev/sda1            /windows/C           ntfs
ro,users,gid=users,umask=0002,nls=utf8 0 0
/dev/sda5            swap                 swap       defaults

I may be having a senior moment and Steve there are no stupid questions
but, I don't understand what you're saying here. Is there something in
the menu.lst that has to do with swap?
