Modifying DTFS root filesystem mount configuration

You cannot modify the mount configuration for a DTFS root filesystem from the Filesystem Manager.

To modify the configuration for these filesystems:

1. Log in as root on the system where you want to change the root filesystem mount configuration.

2. Use the Hardware/Kernel Manager as described in ``Configuration tools''. Select category 10, ``Filesystem configuration.''

   • To enable sync on close, set ROOTSYNC to 1.

   • To disable sync on close, set ROOTSYNC to 0 (default).

   • To enable compression, set ROOTNOCOMP to 0 (default).

   • To disable compression, set ROOTNOCOMP to 1.

   • To enable versioning and set the maximum number (n) of versioned files, set ROOTMAXVDEPTH to a non-zero number.

   • To disable versioning, set ROOTMAXVDEPTH to 0 (default).

   • To set the number of seconds (n) before a file is versioned, set ROOTMINVTIME to n (a non-zero number). The default value of ROOTMINVTIME is 0.

3. Relink the kernel with the new root filesystem parameters -- see ``Relinking the kernel''.

4. Reboot the system by entering:
   
   reboot
