* -confdir The configuration directory .

* -settime Keep checking the time to avoid drift.
+ * -rxmaxmtu Set the max mtu to help with VPN issues.
* -verbose Be chatty.

* -kerndev [OBSOLETE] The kernel device for AFS.
* -dontfork [OBSOLETE] Don't fork off as a new process.
* -daemons The number of background daemons to start (Default: 2).
* -rmtsys Also fires up an afs remote sys call (e.g. pioctl, setpag)
- * support daemon
+ * support daemon
* -chunksize [n] 2^n is the chunksize to be used. 0 is default.
* -dcache The number of data cache entries.
* -biods Number of bkg I/O daemons (AIX3.1 only)
* -prealloc Number of preallocated "small" memory blocks
- * -pininodes Number of inodes which can be spared from inode[] for
