During the installation, I noticed that unlike Debian, Trisquel didn't offer me the option to completely overwrite the disk. It did allow me to write empty space for greater security. But that process only takes a few minutes. Whereas with Debian the completely overwriting entire disk option takes many hours.

Why doesn't Trisquel have this option?

Also, after I had finished my installation I immediately updated. I was told that there was an updated version of grub and that I should choose between the package maintainers version or the current version. The current version was defaulted and so I chose that one. Can somebody explain to me exactly what that was all about? Did I stunt the growth of my grub and therefor jeopardize the security of my system? Why did this happen? It seems like a weird thing to me.

Thanks!

"completely overwrite the disk"

run shred /dev/sda

edit:
just to be clear only do this if you want to remove all data!

And just to be clearer: this is to be run from a live system (such as Trisquel's installation media).

Trisquel uses a modified version of Ubiquity the Ubuntu installer, which will be why you weren't given a Debian 'completely overwrite' option.

IIRC the GRUB2 question was so that you could dual boot to proprietary operating systems without needing to know the automatically generated grub password. If you're not dual booting you have no need to worry. If you have dual boot then a

sudo dpkg-reconfigure grub-pc

Will let you change it to the package maintainers version (just accept the first two dialogs).

Interesting. I wonder why Ubuntu got rid of the "completely overwrite" option. That's lame. I suppose Gnewsense still has the option since it's based off of Debian.

Oh well. I like all of the extra packages that come in the Trisquel repo. Still. It'd be nice to have that option back.

Thanks for the info!

It not so much that they removed it; Ubiquity isn't derived from Debian's installer. It's just that they didn't add it in to Ubiquity.

Anyway, if you want to do it, you can just use the shred command on the HDD before installing.
