Yes, that's what I did as well (installed Gentoo from within a running |
| 17 |
SuSE install), but I've left my SuSE install as a fallback in the |
| 18 |
(increasingly unlikely) event that I bork Gentoo so badly that I can't |
| 19 |
boot it at all (and that the problems are more severe than can be easily |
| 20 |
fixed by just booting a LiveCD and fixing a couple of lines in a config |
| 21 |
file, which is the most typical situation). |
| 22 |
|

May I also point out a very useful SuSE feature that made this even |
| 24 |
easier; if you boot from the SuSE install disk when you have a |
| 25 |
currently-installed SuSE, you can choose to "Install to another |
| 26 |
directory". Basically this *moves* your SuSE install to another |
| 27 |
partition or drive, without doing anything else to it. |
| 28 |
|
| 29 |
So when I went to install Gentoo next to SuSE, I was running SuSE on a |
| 30 |
temp 20GB HDD (temp because I had only installed SuSE because I |
| 31 |
completely broke Gentoo during The Great PAM Debacle, and it was really |
| 32 |
just about as unfixable-- by me-- as Gentoo is ever likely to get, but I |
| 33 |
had no particular intention or desire to keep SuSE on the system; I just |
| 34 |
needed to run something while I reorganized to reinstall Gentoo.... took |
| 35 |
a year, iirc), but intended to install Gentoo (and SuSE) to my |
| 36 |
newly-bought 80GB HDD (and dump the 20 GB drive). So I used that SuSE |
| 37 |
feature to move the current installation to the 80GB drive, and after |
| 38 |
testing, removed the junk drive. So then I had SuSE on the 80GB, and was |
| 39 |
able to go through the regular Alternative Install as normal, installing |
| 40 |
Gentoo to other partitions of the same drive. |
| 41 |
|

SuSE is still in my GRUB menu and bootable, but honestly, I never boot |
| 43 |
into it, and in fact I mainly mount the partition in order to use the |
| 44 |
space on it to back stuff up temporarily. But if I really needed to, I |
| 45 |
could boot it, the kernel is still in /boot, and there's no reason there |
| 46 |
should be a problem doing so (since I do all the backing up to |
| 47 |
/usr/local, where it shouldn't bother anything if I needed to actually |
| 48 |
boot SuSE). |
