Standard btrfs-convert supports in-place conversion from reiserfs.
Btrfs is a great choice - if you want to end up with an unbootable system after a few shapshots have used up all available disk space on the root filesystem, leaving the system unbootable and unrecoverable (and all because it doesn’t use sensible defaults and there is no warning during installation that the defaults need to be tweaked to prevent this).
*you* are able to change the defaults.
Sure, but defaults should just work. Proof that they were wrong are RB words in this thread: «snapper is no longer enabled on small disks. There is a clear warning during installation if you try and force otherwise.» «and snapper is now aware of how much space it is using and tidies up after itself based on space availability»
I presently have 4 boxes with btrfs roots and cannot remember ever a problem with the file system or space available.
But many people had the contrary experience. I have read of many.
and I believe the default space settings have been changed. of course we can continue to throw out the baby with the wash water and never again use btrfs because it was once dangerous and we never checked again.
I don't trust it "not being dangerous" now. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
