Ubuntu 13.10 x64 with emoncms

Remote conversion of 32-bit CentOS 6.3 to 64-bit Ubuntu 13.10

Pretty much any Linux should be fine as long as you have suitable scratch partition for temp Ubuntu install, in this example we're re-using 6GB swap partition. Process is two step, first we do minimal 32-bit Ubuntu install over swap partition, boot system, hack it to 64-bit and finally do final 64-bit Ubuntu install over old CentOS rootfs.

Ubuntu and broken or missing aufs with default kernels

Aufs included in Ubuntu kernels is broken, what a surprise. In addition it has been dropped from newer kernels with claims that overlayfs does exactly same thing. It doesn't and everyone knows it except that one developer who decided it does and can't admit he made mistake. It seems aufs (and overlayfs) in Ubuntu is not really supposed to be used but only be part of install process. If so you guys shouldn't include it outside installer.. WontFix you too.

USB keyboard doesn't work during initramfs with Ubuntu 12.04 / 12.10 / 13.04 after upgrading kernel

Updating Seagate ST3000DM001-9YN166 to CC4H firmware while in external USB 3.0 enclosure

Some time ago I purchased external 3TB USB 3.0 hard disks, TrekStor DataStation maxi light 3TB to be exact. It seem disk models and manufactures used by TrekStor vary, which is no surprise. Therefore I have externally identical disk enclosures with three different models of disks due making three separate purchases over few months.
