[Solved] Clarification request for Btrfs entry on wiki

On http://wiki.archlinux.org/index.php/Btrfs , near the bottom of the page, a method is described for activating Btrfs compression during the Arch install, before package selection, in order to have all those packages installed compressed (in addition to all the data that will be added after first boot of course). The command is

mount -o remount,compress=lzo /dev/sdXY /mnt/target

.

My question: I know that the /dev/sdXY in that command is a place holder, and I should insert the proper path to my disk at that point. But is /mnt/target a placeholder too? If it is, where do I find out the proper mount points?

Thanks

Since you may have different partitions for /, /var, etc and since you can't shouldn't mount all of them on the same place (unless you know what are you doing), i guess that yes it's a placeholder and should be replaced with the path where they already are mounted from the installer.

That's good to know. Now, how do I discover where the installer has mounted them? Probably a silly question but I don't know the answer.

Use mount

Thanks. Switching to another tty and using "mount" works. Or could also use "df" to see what is mounted.
