-
- No I cannot, because I don't have either. :-)
-
- But I believe that it doesn't have substantially changed sincse BSD-Net2.

-
- Here are hierarchies from a few more Unix systems I have (or had) access to.
-
- In the following chart, each column lists differences from the column left
- to it.
-
- BSD-Net2 DEC OSF/1 Linux
-
- Config files /etc
- Single user bins /bin
- Single user root user /sbin
- Temporary files /tmp
-
- Per machine variable /var
- Spool directories /var/spool
- Mail spool /var/mail /var/spool/mail
- Big tmp /var/tmp
- Logfiles /var/log /var/adm
- Accounting files /var/acct /var/adm
- Crash dumps /var/crash /var/adm/crash
-
- Bins /usr/bin
- UCB bins /usr/ucb /usr/bin (3) /usr/bin
- Library files /usr/lib
- Pgms called by pgms /usr/libexec /usr/lbin
- Data files /usr/libdata /usr/lib (1)
- Shared libs -- /usr/shlib /usr/lib
- Programmer's bin, lib /usr/{bin,lib} /usr/ccs/{bin,lib} /usr/{bin,lib}
- Arch. indep. data files /usr/share /usr/lib
- Manuals /usr/share/man (2) /usr/man
- Other stuff /usr/var -> /var
- /usr/spool -> /var/spool
- /usr/adm -> /adm
- /usr/tmp -> /var/tmp
-
- Kit specific (4) -- /usr/kits/KITNAME/... --
- -- /var/kits/KITNAME/... --
-
- Some remarks:
-
- (1) OSF/1 /usr/lib:
- most stuff are just symlinks, like
- libc.a -> ../ccs/lib/libc.a
- tmac -> ../share/lib/tmac
-
- (2) OSF/1 has a symlink
- /usr/man -> /usr/share/man
-
- (3) OSF/1 has a symlink
- /usr/ucb -> /usr/bin
-
- (4) OSF/1 /usr/kits/KITNAME/...
- /var/kits/KITNAME/...
- These are kit specific and can be installed and deleted separately (via
- `setld'). A lot of stuff from /usr is symlinked into these hierarchies.
-
- Hmm.. (after some consideration) from my point of view, the Linux column
- looks best. :-)
