revisiting boot partition and LVM + grub<br> </font> </div> <br>

I am
installing<br>from some dumps of ubuntu jeos 8.04LTS based system, CentOS, possibly trying some installs from<br>Debian 6.04, Fedora 16, ubuntu 10.04, CentOS 6.2 ... I imagine that the grubiness would have to be <br>massaged from a rescue type boot.... (looks like getting/creating an initrd to support loading lvm could be fun...)<br> After reading David's response it looked like there was some <a target="_blank" href="http://ubuntu.com">ubuntu.com</a> reference <br>to the /boot within lvm and the systemrescueCD page seems to have some info as well.... At the<br>moment I haven't read on, am testing my dumps without messing with the partitioning into lvm.<br><br>The idea I am working on is that the flash stick is a little limited on space, so having easy resize <br>capability with /boot might be worthwhile on that media..... Also in general I tend to make <br>/boot small (128M) and have occasionally gotten into trouble with updates.... and cleaning
up kernels ... <br>(particularly with
the ubuntu...)<br><br>-Mike<br>---------------------------------------------------------------------------------------------------------------------------------------<br><br><br>I can't say if there are any distro installers that support it at this<br>point. I don't recall it being an option with Fedora 15, and it's<br>definitely not something the Debian 6.0 installer can handle.<br><br>[I had a big bunch of text in here describing my setup, but it's not<br>really relevant (/boot is in an MD RAID1 mirror, not on a logical<br>volume, and there are _no_ type 8e "partitions" (GPT, baby!).]<br><br>Let us know how it goes.<br><br>- Aaron<br><br><br> </div> </div> </div></div></div></div></body></html>
