comment How to speed up migration from Raid 5 to Raid 6 with mdadm?
After having tried this myself, the version of mdadm I had complained about not specifying the --backup-file option. You should be able to use --force to bypass the error, however it's best to have a backup of the data on your RAID array before doing this! (I didn't try proceeding, so YMMV)

comment Difference between UUID from blkid and mdadm?
really the colon : or dash - are there simply so humans can read the long UUIDs in chunks and not get lost somewhere in the middle. The UUID is really a binary number, and has no dashes or colons. It is implemented in Linux as an unsigned character array: unsigned char uuid_out[16]. Apparently the UUID spec also has an idea of variants and versions, which we can see implemented by setting the most significant byte uuid_out[6] to 4.

Perhaps a better in-practice explanation may be found in the ArchLinux wiki pages: fstab: Identifying Filesystems‌​, and Persistent block device naming: by-uuid.

comment Difference between UUID from blkid and mdadm?
After having gone through the journey firsthand many years ago of why UUIDs are needed (problems booting after drive reordering), and learning about all the complexities of block devices, RAID, LVM, etc... Perhaps a simplified explanation is: Due to the need for the boot system to know how to identify which device to boot from, or how to assemble a RAID or VG, everything gets UUIDs. UUIDs are "Universally Unique IDentifiers" and are generated in Linux here or via libuuid.

comment is there a pastebin service that supports terminal escape sequences?
Good catch! Looks like that link gives a 502 Bad Gateway error currently. It would appear that something changed, and paste.sixteencolors.net no longer is a working URL. Seems that http://sixteencolors.net/ still gives a page that works, however I can't find the pastebin functionality anymore. Seems that they have a web page where you can create ANSI Art here

comment Selectively disabling gvfsd-cdda in Debian Squeeze?
find /usr/share/applications/ -iname '*grip*.desktop' should do it.

comment Selectively disabling gvfsd-cdda in Debian Squeeze?
If you use k3b, it should pop up the dialog with an option to kill the process. It's fine to do so because it'll start up next time you eject/load a cd to automount it. You can always just run pkill gvfsd-cdda manually. Or you could add a context menu option to the .desktop file for grip. An example of how to do this for k3b can be found here. You can adapt it by finding the appropriate grip.desktop file.

comment Is there a tool/website to compare package status in different Linux distributions?
Love this site! It'd be even better if it had some way to link common package names across distros and coorelate this with popularity stats & data (e.g.: The Ubuntu Popularity Contest data)
