Re: [coLinux-devel] Is there a way to increase total memory?

[Michael H. <hal...@ho...>]

Doing it that way gives the following error:

mkswap: error: swap area needs to be at least 40kB
Usage: mkswap [-c] [-v0|-v1] [-pPAGESZ] /dev/name [blocks]


and I've been spoiled with gentoo linux... in order to make a swap all I 
normally need to type is 'mkswap /dev/hdxx'
