remount the install partition during livecd install


Hi,

i would like to remount the destination install partition during a livecd install so that i can mount (remount) it the btrfs partition (/) with the additional options compress=zlib,ssd.

the overall goal is to use the btrfs compression feature right from installation, and not only after system has been installed and i can edit the fstab.

the system i use is sabayon, but i guess at this point in installation most systems are similar.

can anyone help?
thx
Jeff

This isn't particularly newbie. Have you tried going non-newbie ?

Don't worry, it is being looked at by others as well

If you think another sub-forum on LQ would be more appropriate you might want to ask a moderator to move this thread (use the report button to do so).

Hi,

I'm not sure it is possible what you want to do. Aren't the options you want available from the (advanced) install screens?

You might get a better response from the LQ community if you tell us which distro you are trying to install and if this is a regular (as in not automated) install.

Hope this helps.

I've no idea if this is applicable but I remember installing SunOS to an old (New at the time) Sun workstation, Motorola M680xx, pre Sparc CPU. The files were loaded onto the swap partition from which the OS was installed after an auto reboot. Once the final system was booted, the partition reverted to swap and was overwritten.

OK, probably no help at all to you at all, though I note that Live CDs appear to copy all the files over to the hard disk before instalation as well.


Play Bonny!

Actually, this copy over part is the installation.

on some blog i found this recomendation:

mount -o remount,compress,ssd /dev/mapper/target /target -t btrfs

however i wasnt able to properly determine what the path would be in my special case, since im in a live cd environment and i want to remount the root of the target(destination) installation.

When in your install environment, after partitioning and before the actual install to the disk, run
Code:
mount
without any parameters (may be with sudo, I don't know about Sabayon) in a console. This will list all mounted partitions, this way you should easily be able to determine the targets mountpoint. If it will not show up, try this during a test install (means during the actual copying of files)to the harddisk. Once you determined the correct mountpoint and the correct device it should be easy to remount the partition.

Given the lack of detail -- OP doesn't even specify the distro involved -- I would say that this is in the right place.

1ce OP does tell us which distro, we can consider moving this to that distro's sub-forum, assuming it has one.


servercircle,

I'm curious, why did you join LQ?

Are you aware that your quick response -- one which was reported to the mods as "unhelpful" -- knocked this thread off LQ's 0-reply list & thus lessened its exposure to potential answers?

I have to disagree. The OP states in his first post:

Funny how multiple people overlooked that....

Anyway, maybe this will help the OP: How to install Sabayon 5.3 on a btrfs filesystem

You're probably right; although I'd like to plead that OP doesn't explicitly say that s/he is installing Sabayon & that s/he fooled druuna also. :eggonface:
