DEC OSF/1 / Unix / Tru64 File systems

Local filesystems

DEC/Tru64 UNIX >=3.x by default installs filesets root_domain#root, usr_domain#usr, usr_domain#var (Tru64 5.x) and var_domain#var (Tru64/DEC Unix 4.x,3.x), respectively. The /tmp directory is in the root_domain#root fileset and should be cleaned on a daily basis.

OSF/1 >=3.x

Use

crontab -e 

           # system default: 
20 4 * * * /usr/sbin/dirclean -t +2 -o -k s /tmp/
           # alternative:
0 3 * * * /opt/bin/scavenger -t+1 /tmp

to specify regular cleanup.

OSF/1 2.x

Use

vi /usr/spool/cron/crontabs/root

           # system default: 
20 4 * * * find /tmp  -type f -atime +2 -exec rm -f {} \;
           # alternative:
0 3 * * * /opt/bin/scavenger -t+1 /tmp

to specify regular cleanup.

Remote filesystems

are defined to share user, data and scratch files as well as applications. They are mounted via the autofs () or the older automount () mechanism.
Configuration files are (the comments are for explanation only, not allowed in the real world):

/etc/auto.u:

/WWW -rw rs6kf:/userfs/WWW/       # HTML docs, common for all platforms
/c   -rw rs6kf:/userfs/COMMON/    # user filesystem, common for all platforms
/u   -rw rs6kf:/userfs/DUX/MIPS/  # for Mips hardware
/u   -rw rs6kf:/userfs/DUX/ALPHA/ # for Alpha hardware

/etc/auto.d:

bio      -rw rs6kf:/datafs/bio
depot    -rw rs6kf:/depotfs/
swdepot  -rw rs6kf:/swdepotfs
img      -rw rs6kf:/imgfs

/etc/auto.s:
```
bio   -rw rs6kf:/scratch/bio
```

/etc/auto.nfs:

                                            # for Alpha hardware:
local   -ro rs6kf:/applfs/applb01/DUX/ALPHA
install -rw rs6kf:/applfs/applb01/DUX/ALPHA
                                            # for Mips hardware:
local   -ro rs6kf:/applfs/applb01/DUX/MIPS
install -rw rs6kf:/applfs/applb01/DUX/MIPS

/etc/auto.master:

/-   /etc/auto.u          # direct map to allow new users in /u
/s   /etc/auto.s
/d   /etc/auto.d
/nfs /etc/auto.nfs

Note that the various mount points are created automatically.

Automounted filesystems are available via:
- traditional automount
  activated in /etc/rc.config.common (5.x) and /etc/rc.config (4.x,3.x,2.x), respectively, as
```
/usr/sbin/automount -v -f /etc/auto.master
```
  Note that automount should never be send the kill -KILL or kill -INT signal, only kill -TERM
- modern autofsd
  activated in
```
/sbin/rc3.d/S19nfs
```
necessary links:
```
ln -sf /u /usr/users
```
