No, because encrypted partitions hold LVM volumes as well. |

Keeping my mini-distro there, which I use as instant-boot router w/o |
| 34 |
mounting anything. |
| 35 |
Why not keep it on /boot, separate partition or separate initrd? |
| 36 |
I do, each with a bit different setup and purpose. |

Simplier to setup prehaps, but I find it simplier to keep my initrds |
| 49 |
contents in git branches w/ one-click build and deploy script, which I |
| 50 |
find simplier to maintain than ten different paths under /boot. |
| 51 |
|
| 52 |
But this goes completely offtopic. It's not like I seek suggestions for |
| 53 |
my setup, it works perfectly already. |
