Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+IBM's Journaled File System (JFS) for Linux
+JFS Homepage:
+The following mount options are supported:
+iocharset=name Character set to use for converting from Unicode to
+ ASCII. The default is to do no conversion. Use
+ iocharset=utf8 for UTF8 translations. This requires
+ CONFIG_NLS_UTF8 to be set in the kernel .config file.
+ iocharset=none specifies the default behavior explicitly.
+resize=value Resize the volume to <value> blocks. JFS only supports
+ growing a volume, not shrinking it. This option is only
+ valid during a remount, when the volume is mounted
+ read-write. The resize keyword with no value will grow
+ the volume to the full size of the partition.
+nointegrity Do not write to the journal. The primary use of this option
+ is to allow for higher performance when restoring a volume
+ from backup media. The integrity of the volume is not
+ guaranteed if the system abnormally abends.
+integrity Default. Commit metadata changes to the journal. Use this
+ option to remount a volume where the nointegrity option was
+ previously specified in order to restore normal behavior.
+errors=continue Keep going on a filesystem error.
+errors=remount-ro Default. Remount the filesystem read-only on an error.
+errors=panic Panic and halt the machine if an error occurs.
+Please send bugs, comments, cards and letters to
