[Discuss] Reading Linux book

[aldo albanese]

Hi,
First of all, thanks for your previous tips on the Linux box, it was very much appreciated.  I'm reading the different filesystems, when would you use XFS or JFS or ext4.  If I'm correct currently Linux uses ext4, am i right?  From the reading both XFS and JFS look like a great choice.

Thanks,
Aldo

XFS This is a 64-bit, high-performance journaling
   filesystem that provides fast recovery and can
    handle large files efficiently.
JFS This is a 64-bit journaling filesystem that is fast
     and reliable. It is better equipped to handle power
    failures and system crashes.
ext4 The newest default filesystem for Linux distribu-
      tions. It is backwards-compatible with the ext2 and
     ext3 filesystems. Among ext4’s improvements over
        ext3 are journaling, support of volumes of up to
       one exbibyte (EiB) and files up to 16 tebibytes
        (TiB) in size.
