Full CentOS/RH 5.5 + epel repo should build it. No EL6 packages are
needed. But if you try to build the EL6 version one it will not. Build

[CentOS] why i can not put my swap files in /dev?
I tried to create some swap files in /dev directory for my desktop. the dd and mkswap were ok. but when I try to swapon it, i get this: # swapon /dev/myswap swapon: /dev/myswap: Invalid argument but when I mv the file to some other directory like /mnt or /, the swapon works. could sb. tell me why? -- Tang Jianwei ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Thank you and Mogens. and I also think this is the cause.

Re: [CentOS] why i can not put my swap files in /dev?
In the past I only heard that /proc and /sys are RAM directories, now I get /dev as well. thank you.

Well, /dev is *not* a good place for anything but device files. /dev is not a real directory for data files. snip Um, er, what do you mean about it not being a real directory? mark I would say he means real as exists on a hard drive like /home of /var as opposed to virtual as exists in RAM like /proc.
