Title: Dual installation in one filesystem of TCL 2.x and TCL 3.x
Post by: SvOlli on July 20, 2010, 06:47:32 AM

Hello,

For bug hunting and regression testing, I want to create an installation with options to boot both, 2.x and 3.x. Going for a different kernel and initrd is no problem, but is there a recommended way to keep the two "tce"-directories apart from each other, even if they are stored on the same filesystem?

Greetings,
SvOlli

My practice is to keep /tce /tce27 /tcexfce4 directories on a HD ext3 partition and boot system from USB stick defining tce directory with boot option. I have different USB sticks with 2.11, 3.0, etc to start different systems, but all data are stored on HD, including backup, no persistent home used.

It works fine for testing different versions, have different development environment, etc.

It is not dual, it is multiple :)

It would be nice to be able to use a boot code like:

Code: [Select]

tce=LABEL=GREENFOB3/tce3.1rc1

Where GREENFOB3 is the label of my USB stick and it could contain several different tce directories for various versions.

Is there an easy way to do something like this that I am missing?  If not, is this something that could be worked into a future version?

I currently have separate grub entries:

Code: [Select]

kernel /Tiny/boot2/bzImage ... tce=sda3/tc2
and

Code: [Select]

kernel /Tiny/boot3/bzImage ... tce=sda3/tc3
and these work fine side-by-side.

One problem I did have however was when I tried

Code: [Select]

tce=sda3/Tiny/tc3 did I make a mistake somewhere or is the tce= directory required be to be in the root directory (i.e: not within a sub-directory)?

No, deeper directories should work as well. Just did a test with tce=fd0/adir/bdir, worked ok.

Interesting. I have a busy weekend, but I'll try to investigate that further. I'll report back any conclusions in case it helps anyone.

Works for me as well.
